+   greater installed and a webserver which is capable of executing
+   CGI scripts (either based on the .cgi extension, or by placing the
+   script within a specific directory).
 
    You need to have RCS installed. Specifically, "rlog", "rcsdiff",
    and "co". This script was tested against RedHat's rcs-5.7-10.rpm
 
    Note, that the viewcvs.cgi script needs to have READ-ONLY, physical
    access to the CVS repository (or a copy of it).  Therefore, rsh/ssh or
-   pserver access doesn't work yet.
+   pserver access to the repository will not work.
+
+   For the more human readable diff formats you need a modern diff utility.
+   If you are using Linux, this is no problem.  But on commercial unices
+   you might want to install GNU-diff to be able to use unified or 
+   side-by-side diffs.
+
+   If you want to use cvsgraph, you have to obtain and install this
+   separately.  See below.  This was tested with cvsgraph-1.1.2.
 
    For the checkin database to work, you will need MySQL >= 3.22, 
    and the Python DBAPI 2.0 module, MySQLdb.  This was tested with
-   MySQLdb 1.12.
+   MySQLdb 0.9.1.

+ENSCRIPT CONFIGURATION
+----------------------
+
+Enscript is program that can colorize sourcecode of a lot of languages.
+Linux distributions like for example SuSE Linux from at least 7.0
+up to the recently released 7.3 already contain a precompiled and
+configured enscript 1.6.2 package.
+
+1) Download genscript from http://people.ssh.com/mtr/genscript/
+
+2) Configure and compile per instructions with enscript.
+   (I 've not done this, since I'm using the precompiled package
+   delivered with SuSE Linux)
+
+3) Set the 'use_enscript' option in viewcvs.conf to 1.
+
+4) That's it!
+
+5) If you want to colorize exotic languages, you might have to 
+   patch 'lib/viewcvs.py' and add a new highlighting file to enscript.
+   I've done this for Modula-2 and submitted the file to the 
+   enscript maintainer long ago.  If interested in this patch for
+   enscript mailto:pefu@sourceforge.net
+
+
+CVSGRAPH CONFIGURATION
+----------------------
+
+CvsGraph is a program that can display a clickable, graphical tree
+of files in a CVS repository.
+
+WARNING: Under certain circumstances (many revisions of a file
+or many branches or both) cvsgraph can generate very huge images.
+Especially on thin clients these images may crash the Web-Browser.
+Currently there is no known way to avoid this behavior of cvsgraph.
+So you have been warned!  
+
+Nevertheless cvsgraph can be quite helpful on repositories with 
+a reasonable number of revisions and branches.
+
+1) Install viewcvs according to instructions in 'INSTALLING
+   VIEWCVS' section above.  The installation directory is where
+   the 'viewcvs-install' script copied and configured the viewcvs
+   programs.
+
+2) Download CvsGraph from http://www.akhphd.au.dk/~bertho/cvsgraph/
+
+3) Configure and compile per instructions with CvsGraph.  I had
+   problems with 'configure' finding the gd library.  Had to create
+   a link from libgd.so to libgd.do.4.0.0.   On Solaris you might
+   want to edit the link command line and add the option -R if 
+   you have you libraries at non-standard location.
+
+4) Place the 'cvsgraph' executable into a directory readable by the
+   userid running the web server. (default is '/usr/local/bin' if
+   you simply type 'make install' in the cvsgraph directory).
+
+5) Check the setting of the 'cvsgraph_path' option in viewcvs.conf:
+   /usr/local/bin/ is most often NOT contained in $PATH of the
+   webserver process (e.g. Apache), so you will have to edit this.  
+   Set the 'use_cvsgraph' option in viewcvs.conf to 1.
+
+6) That's it!
+
+7) There is a file <VIEWCVS_INSTALLATION_DIRECTORY>/cvsgraph.conf that
+   you may want to edit if desired to set color and font characteristics.
+   See the cvsgraph.conf documentation.  No edits are required in
+   cvsgraph.conf for operation with viewcvs.

+
+Class SequenceMatcher
+
+SequenceMatcher is a flexible class for comparing pairs of sequences of any
+type, so long as the sequence elements are hashable.  The basic algorithm
+predates, and is a little fancier than, an algorithm published in the late
+1980's by Ratcliff and Obershelp under the hyperbolic name "gestalt pattern
+matching".  The basic idea is to find the longest contiguous matching
+subsequence that contains no "junk" elements (R-O doesn't address junk).
+The same idea is then applied recursively to the pieces of the sequences to
+the left and to the right of the matching subsequence.  This does not yield
+minimal edit sequences, but does tend to yield matches that "look right"
+to people.
+
+Example, comparing two strings, and considering blanks to be "junk":
+
+>>> s = SequenceMatcher(lambda x: x == " ",
+...                     "private Thread currentThread;",
+...                     "private volatile Thread currentThread;")
+>>>
+
+.ratio() returns a float in [0, 1], measuring the "similarity" of the
+sequences.  As a rule of thumb, a .ratio() value over 0.6 means the
+sequences are close matches:
+
+>>> print round(s.ratio(), 3)
+0.866
+>>>
+
+If you're only interested in where the sequences match,
+.get_matching_blocks() is handy:
+
+>>> for block in s.get_matching_blocks():
+...     print "a[%d] and b[%d] match for %d elements" % block
+a[0] and b[0] match for 8 elements
+a[8] and b[17] match for 6 elements
+a[14] and b[23] match for 15 elements
+a[29] and b[38] match for 0 elements
+
+Note that the last tuple returned by .get_matching_blocks() is always a
+dummy, (len(a), len(b), 0), and this is the only case in which the last
+tuple element (number of elements matched) is 0.
+
+If you want to know how to change the first sequence into the second, use
+.get_opcodes():
+
+>>> for opcode in s.get_opcodes():
+...     print "%6s a[%d:%d] b[%d:%d]" % opcode
+ equal a[0:8] b[0:8]
+insert a[8:8] b[8:17]
+ equal a[8:14] b[17:23]
+ equal a[14:29] b[23:38]
+
+See Tools/scripts/ndiff.py for a fancy human-friendly file differencer,
+which uses SequenceMatcher both to view files as sequences of lines, and
+lines as sequences of characters.
+
+See also function get_close_matches() in this module, which shows how
+simple code building on SequenceMatcher can be used to do useful work.
+
+Timing:  Basic R-O is cubic time worst case and quadratic time expected
+case.  SequenceMatcher is quadratic time for the worst case and has
+expected-case behavior dependent in a complicated way on how many
+elements the sequences have in common; best case time is linear.
+
+SequenceMatcher methods:
+
+__init__(isjunk=None, a='', b='')
+    Construct a SequenceMatcher.
+
+    Optional arg isjunk is None (the default), or a one-argument function
+    that takes a sequence element and returns true iff the element is junk.
+    None is equivalent to passing "lambda x: 0", i.e. no elements are
+    considered to be junk.  For example, pass
+        lambda x: x in " \\t"
+    if you're comparing lines as sequences of characters, and don't want to
+    synch up on blanks or hard tabs.
+
+    Optional arg a is the first of two sequences to be compared.  By
+    default, an empty string.  The elements of a must be hashable.
+
+    Optional arg b is the second of two sequences to be compared.  By
+    default, an empty string.  The elements of b must be hashable.
+
+set_seqs(a, b)
+    Set the two sequences to be compared.
+
+    >>> s = SequenceMatcher()
+    >>> s.set_seqs("abcd", "bcde")
+    >>> s.ratio()
+    0.75
+
+set_seq1(a)
+    Set the first sequence to be compared.
+
+    The second sequence to be compared is not changed.
+
+    >>> s = SequenceMatcher(None, "abcd", "bcde")
+    >>> s.ratio()
+    0.75
+    >>> s.set_seq1("bcde")
+    >>> s.ratio()
+    1.0
+    >>>
+
+    SequenceMatcher computes and caches detailed information about the
+    second sequence, so if you want to compare one sequence S against many
+    sequences, use .set_seq2(S) once and call .set_seq1(x) repeatedly for
+    each of the other sequences.
+
+    See also set_seqs() and set_seq2().
+
+set_seq2(b)
+    Set the second sequence to be compared.
+
+    The first sequence to be compared is not changed.
+
+    >>> s = SequenceMatcher(None, "abcd", "bcde")
+    >>> s.ratio()
+    0.75
+    >>> s.set_seq2("abcd")
+    >>> s.ratio()
+    1.0

+    each of the other sequences.
+
+    See also set_seqs() and set_seq1().
+
+find_longest_match(alo, ahi, blo, bhi)
+    Find longest matching block in a[alo:ahi] and b[blo:bhi].
+
+    If isjunk is not defined:
+
+    Return (i,j,k) such that a[i:i+k] is equal to b[j:j+k], where
+        alo <= i <= i+k <= ahi
+        blo <= j <= j+k <= bhi
+    and for all (i',j',k') meeting those conditions,
+        k >= k'
+        i <= i'
+        and if i == i', j <= j'
+
+    In other words, of all maximal matching blocks, return one that starts
+    earliest in a, and of all those maximal matching blocks that start
+    earliest in a, return the one that starts earliest in b.
+
+    >>> s = SequenceMatcher(None, " abcd", "abcd abcd")
+    >>> s.find_longest_match(0, 5, 0, 9)
+    (0, 4, 5)
+
+    If isjunk is defined, first the longest matching block is determined as
+    above, but with the additional restriction that no junk element appears
+    in the block.  Then that block is extended as far as possible by
+    matching (only) junk elements on both sides.  So the resulting block
+    never matches on junk except as identical junk happens to be adjacent
+    to an "interesting" match.
+
+    Here's the same example as before, but considering blanks to be junk.
+    That prevents " abcd" from matching the " abcd" at the tail end of the
+    second sequence directly.  Instead only the "abcd" can match, and
+    matches the leftmost "abcd" in the second sequence:
+
+    >>> s = SequenceMatcher(lambda x: x==" ", " abcd", "abcd abcd")
+    >>> s.find_longest_match(0, 5, 0, 9)
+    (1, 0, 4)
+
+    If no blocks match, return (alo, blo, 0).
+
+    >>> s = SequenceMatcher(None, "ab", "c")
+    >>> s.find_longest_match(0, 2, 0, 1)
+    (0, 0, 0)
+
+get_matching_blocks()
+    Return list of triples describing matching subsequences.
+
+    Each triple is of the form (i, j, n), and means that
+    a[i:i+n] == b[j:j+n].  The triples are monotonically increasing in i
+    and in j.
+
+    The last triple is a dummy, (len(a), len(b), 0), and is the only triple
+    with n==0.
+
+    >>> s = SequenceMatcher(None, "abxcd", "abcd")
+    >>> s.get_matching_blocks()
+    [(0, 0, 2), (3, 2, 2), (5, 4, 0)]
+
+get_opcodes()
+    Return list of 5-tuples describing how to turn a into b.
+
+    Each tuple is of the form (tag, i1, i2, j1, j2).  The first tuple has
+    i1 == j1 == 0, and remaining tuples have i1 == the i2 from the tuple
+    preceding it, and likewise for j1 == the previous j2.
+
+    The tags are strings, with these meanings:
+
+    'replace':  a[i1:i2] should be replaced by b[j1:j2]
+    'delete':   a[i1:i2] should be deleted.
+                Note that j1==j2 in this case.
+    'insert':   b[j1:j2] should be inserted at a[i1:i1].
+                Note that i1==i2 in this case.
+    'equal':    a[i1:i2] == b[j1:j2]
+
+    >>> a = "qabxcd"
+    >>> b = "abycdf"
+    >>> s = SequenceMatcher(None, a, b)
+    >>> for tag, i1, i2, j1, j2 in s.get_opcodes():
+    ...    print ("%7s a[%d:%d] (%s) b[%d:%d] (%s)" %
+    ...           (tag, i1, i2, a[i1:i2], j1, j2, b[j1:j2]))
+     delete a[0:1] (q) b[0:0] ()
+      equal a[1:3] (ab) b[0:2] (ab)
+    replace a[3:4] (x) b[2:3] (y)
+      equal a[4:6] (cd) b[3:5] (cd)
+     insert a[6:6] () b[5:6] (f)
+
+ratio()
+    Return a measure of the sequences' similarity (float in [0,1]).
+
+    Where T is the total number of elements in both sequences, and M is the
+    number of matches, this is 2,0*M / T. Note that this is 1 if the
+    sequences are identical, and 0 if they have nothing in common.
+
+    .ratio() is expensive to compute if you haven't already computed
+    .get_matching_blocks() or .get_opcodes(), in which case you may want to
+    try .quick_ratio() or .real_quick_ratio() first to get an upper bound.
+
+    >>> s = SequenceMatcher(None, "abcd", "bcde")
+    >>> s.ratio()
+    0.75
+    >>> s.quick_ratio()
+    0.75
+    >>> s.real_quick_ratio()
+    1.0
+
+quick_ratio()
+    Return an upper bound on .ratio() relatively quickly.
+
+    This isn't defined beyond that it is an upper bound on .ratio(), and
+    is faster to compute.
+
+real_quick_ratio():
+    Return an upper bound on ratio() very quickly.
+
+    This isn't defined beyond that it is an upper bound on .ratio(), and
+    is faster to compute than either .ratio() or .quick_ratio().

+"""ezt.py -- easy templating
+
+ezt templates are very similar to standard HTML files.  But additionaly
+they contain directives sprinkled in between.  With these directives
+it possible to generate the dynamic content from the ezt templates.
+
+These directives are enclosed in square brackets.  If you are a 
+C-programmer, you might be familar with the #ifdef directives of the
+C preprocessor 'cpp'.  ezt provides a similar concept for HTML.  Additionally 
+EZT has a 'for' directive, which allows to iterate (repeat) certain 
+subsections of the template according to sequence of data items
+provided by the application.
+
+The HTML rendering is performed by the method generate() of the Template
+class.  Building template instances can either be done using external
+EZT files (convention: use the suffix .ezt for such files):
+
+    >>> template = Template("../templates/log.ezt")
+
+or by calling the parse() method of a template instance directly with 
+a EZT template string:
+
+    >>> template = Template()
+    >>> template.parse('''<html><head>
+    ... <title>[title_string]</title></head>
+    ... <body><h1>[title_string]</h1>
+    ...    [for a_sequence] <p>[a_sequence]</p>
+    ...    [end] <hr>
+    ...    The [person] is [if-any state]in[else]out[end].
+    ... </body>
+    ... </html>
+    ... ''')
+
+The application should build a dictionary 'data' and pass it together
+with the output fileobject to the templates generate method:
+
+    >>> data = {'title_string' : "A Dummy Page",
+    ...         'a_sequence' : ['list item 1', 'list item 2', 'another element'],
+    ...         'person': "doctor",
+    ...         'state' : None }
+    >>> import sys
+    >>> template.generate(sys.stdout, data)
+    <html><head>
+    <title>A Dummy Page</title></head>
+    <body><h1>A Dummy Page</h1>
+     <p>list item 1</p>
+     <p>list item 2</p>
+     <p>another element</p>
+     <hr>
+    The doctor is out.
+    </body>
+    </html>
+
+Directives
+==========
+
+ Several directives allow the use of dotted qualified names refering to objects
+ or attributes of objects contained in the data dictionary given to the 
+ .generate() method.
+
+ Simple directives
+ -----------------
+
+   [QUAL_NAME]
+
+   This directive is simply replaced by the value of identifier from the data 
+   dictionary.  QUAL_NAME might be a dotted qualified name refering to some
+   instance attribute of objects contained in the dats dictionary.
+   Numbers are converted to string though.
+
+   [include "filename"]  or [include QUAL_NAME]
+
+   This directive is replaced by content of the named include file.
+
+ Block directives
+ ----------------
+
+   [for QUAL_NAME] ... [end]
+   
+   The text within the [for ...] directive and the corresponding [end]
+   is repeated for each element in the sequence referred to by the qualified
+   name in the for directive.  Within the for block this identifiers now 
+   refers to the actual item indexed by this loop iteration.
+
+   [if-any QUAL_NAME] ... [else] ... [end]
+
+   Test if the value QUAL_NAME is not None or an empty string or list.  
+   The [else] clause is optional.  CAUTION: Numeric values are converted to string,
+   so if QUAL_NAME refers to a numeric value 0, the then-clause is
+   substituted!
+
+   [if-index odd] ... [else] ... [end]
+   [if-index even] ... [else] ... [end]
+   [if-index first] ... [else] ... [end]
+   [if-index last] ... [else] ... [end]
+   [if-index NUMBER] ... [else] ... [end]
+
+   These five directives work similar to [if-any], but are only useful 
+   within a [for ...]-block (see above).  The odd/even directives are 
+   for example useful to choose different background colors for adjacent rows 
+   in a table.  Similar the first/last directives might be used to
+   remove certain parts (for example "Diff to previous" doesn't make sense,
+   if there is no previous).
+
+   [is QUAL_NAME STRING] ... [else] ... [end]
+   [is QUAL_NAME QUAL_NAME] ... [else] ... [end]
+
+   The [is ...] directive is similar to the other conditional directives
+   above.  But it allows to compare two value references or a value reference
+   with some constant string.

+# SequenceMatcher tries to compute a "human-friendly diff" between
+# two sequences (chiefly picturing a file as a sequence of lines,
+# and a line as a sequence of characters, here).  Unlike e.g. UNIX(tm)
+# diff, the fundamental notion is the longest *contiguous* & junk-free
+# matching subsequence.  That's what catches peoples' eyes.  The
+# Windows(tm) windiff has another interesting notion, pairing up elements
+# that appear uniquely in each sequence.  That, and the method here,
+# appear to yield more intuitive difference reports than does diff.  This
+# method appears to be the least vulnerable to synching up on blocks
+# of "junk lines", though (like blank lines in ordinary text files,
+# or maybe "<P>" lines in HTML files).  That may be because this is
+# the only method of the 3 that has a *concept* of "junk" <wink>.
+#
+# Note that ndiff makes no claim to produce a *minimal* diff.  To the
+# contrary, minimal diffs are often counter-intuitive, because they
+# synch up anywhere possible, sometimes accidental matches 100 pages
+# apart.  Restricting synch points to contiguous matches preserves some
+# notion of locality, at the occasional cost of producing a longer diff.
+#
+# With respect to junk, an earlier version of ndiff simply refused to
+# *start* a match with a junk element.  The result was cases like this:
+#     before: private Thread currentThread;
+#     after:  private volatile Thread currentThread;
+# If you consider whitespace to be junk, the longest contiguous match
+# not starting with junk is "e Thread currentThread".  So ndiff reported
+# that "e volatil" was inserted between the 't' and the 'e' in "private".
+# While an accurate view, to people that's absurd.  The current version
+# looks for matching blocks that are entirely junk-free, then extends the
+# longest one of those as far as possible but only with matching junk.
+# So now "currentThread" is matched, then extended to suck up the
+# preceding blank; then "private" is matched, and extended to suck up the
+# following blank; then "Thread" is matched; and finally ndiff reports
+# that "volatile " was inserted before "Thread".  The only quibble
+# remaining is that perhaps it was really the case that " volatile"
+# was inserted after "private".  I can live with that <wink>.
+#
+# NOTE on junk:  the module-level names
+#    IS_LINE_JUNK
+#    IS_CHARACTER_JUNK
+# can be set to any functions you like.  The first one should accept
+# a single string argument, and return true iff the string is junk.
+# The default is whether the regexp r"\s*#?\s*$" matches (i.e., a
+# line without visible characters, except for at most one splat).
+# The second should accept a string of length 1 etc.  The default is
+# whether the character is a blank or tab (note: bad idea to include
+# newline in this!).
+#
+# After setting those, you can call fcompare(f1name, f2name) with the
+# names of the files you want to compare.  The difference report
+# is sent to stdout.  Or you can call main(args), passing what would
+# have been in sys.argv[1:] had the cmd-line form been used.

+    Select your parameters for querying the CVS commit database.  You
+    can search for multiple matches by typing a comma-seperated list
+    into the text fields.  Regular expressions, and wildcards are also
+    supported.  Blank text input fields are treated as wildcards.
+  </p>
+  <p>
+    Any of the text entry fields can take a comma-seperated list of
+    search arguments.  For example, to search for all commits from
+    authors <i>jpaint</i> and <i>gstein</i>, just type: <b>jpaint,
+    gstein</b> in the <i>Author</i> input box.  If you are searching
+    for items containing spaces or quotes, you will need to quote your
+    request.  For example, the same search above with quotes is:
+    <b>"jpaint", "gstein"</b>.
+  </p>
+  <p>                           
+
+    Wildcard and regular expression searches are entered in a similar
+    way to the quoted requests.  You must quote any wildcard or
+    regular expression request, and a command charactor preceeds the
+    first quote.  The command charactor <b>l</b> is for wildcard
+    searches, and the wildcard charactor is a percent (<b>%</b>).  The
+    command charactor for regular expressions is <b>r</b>, and is
+    passed directly to MySQL, so you'll need to refer to the MySQL
+    manual for the exact regex syntax.  It is very similar to Perl.  A
+    wildard search for all files with a <i>.py</i> extention is:
+    <b>l"%.py"</b> in the <i>File</i> input box.  The same search done
+    with a regular expression is: <b>r".*\.py"</b>.
+  </p>
+  <p>                  
+    All search types can be mixed, as long as they are seperated by
+    commas.
+  </p>

+      <p>
+      Contributions to ViewCVS are very welcome.
+      </p>
+
+      <h2>Getting Started</h2>
+      <p>
+      Some basic knowledge about <a href="http://www.python.org"><i>Python</i></a> and
+      development Tools like <code>diff</code> is required.  Best is you start
+      with a fresh snapshot, which you may obtain from the 
+      <a href="http://sourceforge.net/cvs/?group_id=18760">CVS-Repository</a> 
+      at SourceForge.
+      </p>
+
+      <h2>Testing and reporting</h2>
+      <p>
+      Testing usability and the installation process on different platforms is
+      also a valuable contribution.  Please report your results back to 
+      us developers.  But always tell us, which version of ViewCVS
+      you used on which platform.  
+      </p><p>
+      If you are using the latest current development version please note 
+      the date of your latest download or cvs update when reporting.
+      </p>
+      
+      <h2>Does a Certain Coding Style Guide apply?</h2>
+      <p>
+      Maintain whatever style is present in the code being modified.  New
+      code can use anything sane (which generally means 
+      <a href="http://python.sourceforge.net/peps/pep-0008.html"><i>PEP&nbsp;8</i></a>).
+      Greg's only real peeve is if someone writes a function call as:  
+      <code>some_func&nbsp;(args)</code>  -- that space is Huge Badness. 
+      Otherwise... <i>shrug</i>.
+      </p>
+
+      <h2>Submitting patches</h2>
+      <p>
+      Please use the
+      <a href="http://sourceforge.net/tracker/?func=add&group_id=18760&atid=318760">SourceForge&nbsp;project&nbsp;patch&nbsp;manager</a>
+      to submit your patches.  Unified context diffs relative to the latest 
+      development version are preferred.
+      </p><p>
+      If you have commit access, then you should know what
+      you're doing.  Just make changes directly.  Subscribing to
+      the <a href="http://mailman.lyra.org/mailman/listinfo/viewcvs-dev"><i>developer&nbsp;mailing&nbsp;list</i></a> 
+      is recommended in any case.
+      </p>
+
+      <h2>Preserving security</h2>
+      <p>
+      Since ViewCVS is used in the internet, security is a major issue.
+      If you need to pass data from the request into an external program, 
+      please don't use <code>os.system()</code> or <code>os.popen()</code>.
+      Please use the module <code>lib/popen</code> that comes with ViewCVS
+      instead.
+      </p>
+
+      <h2>Adding new features</h2>
+      <p>
+      If a new file or module is added, a new line in the installer program
+      <code>viewcvs-install</code> is required.
+      </p><p>
+      The library subdirectory contains a module <code>debug</code>, which may
+      useful to make performance tests.
+      </p><p>
+      If you need a new configuration option think carefully, into 
+      which section it belongs.  Try to keep the content of 
+      <code>cgi/viewcvs.conf.dist</code> file and the library module
+      <code>lib/config.py</code> in sync.
+      </p>
+
+      <h2>Hacking on templates</h2>
+      <p>
+      The library module <code>ezt</code> contains a module doc string which
+      describes the directives used in the HTML templates, which can be found
+      in the <code>templates</code> sub directory.
+      </p>
+
+      <h2>Cutting a release</h2>
+      <p>
+      Also there actually is a script <code>tools/make-release</code>, 
+      which creates a release directory, all other steps required to get 
+      a ViewCVS release out of the door will be currently executed manually 
+      by Greg Stein.
+      </p><p>
+      Nevertheless in case he ever wants to retire from this job, it is 
+      probably a good idea to write the procedure down here:
+      <ol>
+        <li>Add a new subsection to the file 
+	 <code>website/upgrading.html</code> describing all user visible 
+	 changes for users of previous releases of ViewCVS.
+        <li>Test, Test, Test!  At the time of this writing (0.8-dev) there
+	 is no automatic testsuite available.  So just run with permuting
+	 different <code>viewcvs.conf</code> settings and ... pray.
+	<li>Review any <a 
+	 href="http://sourceforge.net/tracker/?atid=118760&group_id=18760&func=browse">
+	 bug reports, that are still marked open.</a>
+	<li>Edit the file <code>lib/viewcvs.py</code>  and remove the
+	 <tt>"-dev"</tt> suffix from <code>__version__</code>.  The remainder 
+	 should be of the form X.Y, where X is a positive number and 
+	 Y is a single digit.
+	<li>commit this changed version of <code>lib/viewcvs.py</code>
+	 and than <code>cvs tag V</code><i>X</i><code>_</code><i>Y</i>, where
+	 <i>X</i> and <i>Y</i> should be replaced by the release number
+	 from above.  If a developer is willing to volunteer as a
+	 bug fix patch release manager, it is now possible to start here
+	 at this point with a feature freezed branch using the command 
+	 <blockquote>
+         <code>cvs tag -b V</code><i>X</i><code>_</code><i>Y</i><code>_maint</code>
+	 </blockquote>
+	<li>go into an empty directory and run the command:
+	  <blockquote>
+	   <code>tools/make-release V</code><i>X_Y</i> <code>viewcvs-</code><i>X.Y</i>
+	  </blockquote>
+	 This step requires anonymous CVS access to repository at SourceForge.
+	<li>pack the content of this <code>viewcvs-</code><i>X.Y</i> directory
+	 into a tarball.  
+	<li>Upload the created tarball into the download files section of the
+	 ViewCVS project at SourceForge. 
+	 <br><b>Greg:</b><i>Could you please elaborate this step?</i>
+	<li>Edit the file <code>lib/viewcvs.py</code> again and this time 
+	 increment the <code>__version__</code> for the next release cycle,
+	 again append the <code>"-dev"</code> to the version and again
+	 <blockquote>
+	  <code>cvs commit -m "new release cycle begins" lib/viewcvs.py</code>.
+	 </blockquote>
+	<li>Write an announcement explaining all the cool new features
+	  and put it out to:
+	  <ul>
+	   <li><a href="http://www.freshmeat.net"><i>www.freshmeat.net</i></a>
+	   <li><a href="http://www.vex.net/parnassus/apyllo.py?i=91022454"><i>Vaults of Parnassus</i></a>
+	   <li><a href="news:comp.lang.python">comp.lang.python</a>
+	   <li><i>Where else? I dunno. Suggestions welcome.</i>

+    Select your parameters for querying the CVS commit database in the
+    form at the top of the page.  You
+    can search for multiple matches by typing a comma-seperated list
+    into the text fields.  Regular expressions, and wildcards are also
+    supported.  Blank text input fields are treated as wildcards.
+  </p>
+  <p>
+    Any of the text entry fields can take a comma-seperated list of
+    search arguments.  For example, to search for all commits from
+    authors <i>jpaint</i> and <i>gstein</i>, just type: <code>jpaint,
+    gstein</code> in the <i>Author</i> input box.  If you are searching
+    for items containing spaces or quotes, you will need to quote your
+    request.  For example, the same search above with quotes is:
+    <code>"jpaint", "gstein"</code>.
+  </p>
+  <p>                           
+    Wildcard and regular expression searches are entered in a similar
+    way to the quoted requests.  You must quote any wildcard or
+    regular expression request, and a command character preceeds the
+    first quote.  The command character <code>l</code>(lowercase L) is for wildcard
+    searches, and the wildcard character is a percent (<code>%</code>).  The
+    command character for regular expressions is <code>r</code>, and is
+    passed directly to MySQL, so you'll need to refer to the MySQL
+    manual for the exact regex syntax.  It is very similar to Perl.  A
+    wildard search for all files with a <i>.py</i> extention is:
+    <code>l"%.py"</code> in the <i>File</i> input box.  The same search done
+    with a regular expression is: <code>r".*\.py"</code>.
+  </p>
+  <p>                  
+    All search types can be mixed, as long as they are seperated by
+    commas.

-      The ViewCVS software was inspired by
-      <a href="http://stud.fh-heilbronn.de/~zeller/cgi/cvsweb.cgi/"><i>cvsweb</i></a>
-      (by <a href="mailto:zeller@think.de">Henner Zeller</a>).
-      I wanted to make some changes and updates, but cvsweb was
-      implemented in Perl. While I can manage some Perl, cvsweb was
-      rather unmaintainable for me. So I undertook the

       ViewCVS can browse directories, change logs, and specific
       revisions of files. It can display diffs between versions and
-      show selections of files based on tags or branches. In addition, 
-      ViewCVS has "annotation" or "blame" support, and the beginnings
-      of Bonsai-like query facilities.
-    </p>
-    <p>
-      ViewCVS is currently at version 0.6. It was a port of the cvsweb
-      script, but has had numerous cleanups and other modifications,
-      based on some of Python's strengths. There is still some minor
-      "badness" remaining from the Perl code, but I've been working on
-      flushing that out, while adding new features. Currently, the
-      functionality of ViewCVS surpasses that of cvsweb.

+      consider, change, or handle when upgrading an existing ViewCVS
+      installation to a newer version.
+    </p>
+    <p>
+      It is always recommended to install the new version in a fresh directory
+      and to carefully compare the configuration files.  A possible approach
+      is to name the directories <code>/usr/local/viewcvs-0.6</code>, 
+      <code>/usr/local/viewcvs-0.7</code> and so on and than create a 
+      symbolic link <code>viewcvs</code> pointing to the production 
+      version.  This way you can easily test several versions and switch
+      back, if your users start to complain.

+    </p>
+
+    <h3>Configuration Options</h3>
+    <p>
+      More templates were introduced in version 0.8 of the software,
+      which made many of the configuration options obsolete. This
+      section covers which options were removed. If you made any
+      changes to these options, then you will need to make
+      corresponding changes in the templates.
+    </p>
+    <blockquote>

+	  <strong>diff_heading</strong>,

+        <dt>Colors: <strong>nav_header</strong>
+          and <strong>alt_background</strong></dt>

+	  <p></p>

+	  Images:
+          <strong>back_icon</strong>,
+          <strong>dir_icon</strong>,
+          and <strong>file_icon</strong>
+        </dt>
+	<dd>
+	  These options have been incorporated into the
+	  <code>directory.ezt</code>, <code>header.ezt</code>,
+	  <code>log.ezt</code>, <code>log_table.ezt</code>, and
+	  <code>query.ezt</code> templates.
+
+	  <p></p>
+	</dd>
+
+	<dt><strong>use_java_script</strong>
+          and <strong>open_extern_window</strong></dt>
+	<dd>
+	  The templates now use JavaScript in all applicable places,
+	  and open external windows for most downloading and viewing
+	  of files. If you wish to not use JavaScript and/or external
+	  windows, then remove the feature(s) from the templates.
+
+	  <p></p>
+	</dd>
+
+	<dt><strong>show_author</strong></dt>
+	<dd>
+          Changing this option would be quite strange and rare. If you
+          do not want to show the author for the revisions, then you
+          should remove it from the various templates.
+
+	  <p></p>
+	</dd>
+
+	<dt><strong>hide_non_readable</strong></dt>
+	<dd>
+          This option was never used, so it has been removed.
+
+	  <p></p>
+	</dd>
+
+	<dt><strong>flip_links_in_dirview</strong></dt>
+	<dd>
+          This option is no longer available. If you want the links in
+          your directory view flipped, then you may use the
+          <code>dir_alternate.ezt</code> template.
+
+	  <p></p>
+	</dd>

+
+    <h3>Template Variables</h3>
+    <p>
+      Some template variables that were available in 0.8 have been
+      removed in 0.9. If you have custom templates that refer to these
+      variables, then you will need to modify your templates.
+    </p>
+
+	  <blockquote>
+	    <dl>
+	      <dt><code>directory.ezt</code>: <var>headers</var></dt>
+	      <dd>
+		The headers are now listed explicitly in the template,
+		rather than made available through a list.
+		<p></p>
+	      </dd>
+
+	      <dt>
+		<code>directory.ezt</code>:
+		<var>rows.cols</var>,
+		and <var>rows.span</var>
+	      </dt>
+	      <dd>
+		These variables were used in conjunction with the
+		<var>headers</var> variable to control the column
+		displays. This is now controlled explicitly within the
+		templates.
+		<p></p>
+	      </dd>
+
+	      <dt><code>directory.ezt</code>:
+		<var>rev_in_front</var></dt>
+	      <dd>
+		This was used to indicate that revision links should
+		be used in the first column, rather than in their
+		standard place in the second column. Changing the
+		links should now be done in the template, rather than
+		according to this variable. You may want to look at
+		the <code>dir_alternate.ezt</code> template, which has
+		the revision in front.
+		<p></p>
+	      </dd>
+
+	      <dt><code>directory.ezt</code>:
+		<var>rows.attic</var>
+		and <var>rows.hide_attic_href</var></dt>
+	      <dd>
+		These variable were used to manage the hide and
+		showing of the contents of the <code>Attic/</code>
+		subdirectory. Several new variables were introduced
+		which can be used to replace this functionality:
+		<var>show_attic_href</var>,
+		<var>hide_attic_href</var>, and <var>rows.state</var>.

+    <h2><a name="from7">Upgrading from ViewCVS 0.7 or earlier</a></h2>
+    <p>
+      This section discusses how to upgrade ViewCVS 0.7, or earlier,
+      to 0.8 or a later version of the software.
+    </p>
+    <p>
+      <strong>NOTE:</strong> these changes will bring you up to the
+      requirements of version 0.8. You must also follow the directions
+      for <a href="#from8">upgrading from 0.8</a>.
+    </p>
+
+    <h3>Configuration Options</h3>
+    <p>
+      The largest change from 0.7 to 0.8, that you will need to deal
+      with, is the introduction of templates. This shifted many
+      configuration file options into the templates, for more direct
+      editing of the output style, colors, and layout. Below is a list 
+      of options that no longer exist, and where you can find their
+      counterpart in the current version of ViewCVS.
+    </p>
+    <p>
+      The following options have all been removed in ViewCVS 0.8. If
+      you made local changes to your ViewCVS configuration, then you
+      will need to edit templates in the <code>templates/</code>
+      subdirectory.
+    </p>
