#
|
|
# CONFIGURATION
|
|
# -------------
|
|
#
|
|
# There are three forms of configuration:
|
|
#
|
|
# 1. edit the viewvc.conf created by the viewvc-install(er)
|
|
# 2. as (1), but delete all unchanged entries from viewvc.conf
|
|
# 3. do not use viewvc.conf and just edit the defaults in this file
|
|
#
|
|
# Most users will want to use (1), but there are slight speed advantages
|
|
# to the other two options. Note that viewvc.conf values are a bit easier
|
|
# to work with since it is raw text, rather than python literal values.
|
|
#
|
|
#
|
|
# A WORD ABOUT OPTION LAYERING/OVERRIDES
|
|
# --------------------------------------
|
|
#
|
|
# ViewVC has three "layers" of configuration options:
|
|
#
|
|
# 1. base configuration options - very basic configuration bits
|
|
# found in sections like 'general', 'options', etc.
|
|
# 2. vhost overrides - these options overlay/override the base
|
|
# configuration on a per-vhost basis.
|
|
# 3. root overrides - these options overlay/override the base
|
|
# configuration and vhost overrides on a per-root basis.
|
|
#
|
|
# Here's a diagram of the valid overlays/overrides:
|
|
#
