+Some work is needed to include these into the automated test suite.
+For now, run them manually according to these instructions:
+
+Compile OpenSCAD in debug mode. This will give console output related to module caching, e.g.:
+/path/to/used.scad: 0x103612f70
+Module cache size: 1 modules
+
+Test1:
+------
+
+o Open use.scad
+o Compile twice (F5) - check that module reference is the same
+
+Test2:
+------
+
+o Open use.scad
+o Compile (F5)
+o touch used.scad
+o Compile (F5) - check that the module reference changed
+
+Test3:
+------
+
+o Open use-mcad.scad
+o Compile (F5)
+o Check that you get a rounded box
+
+Test4:
+------
+
+o Open usenonexsistingfile.scad
+o Compile (F5)
+o Verify that you get: WARNING: Can't open 'use' file 'nofile.scad'.
+
+Test5:
+------
+
+o Open moduleoverload.scad
+o Compile (F5)
+o Verify that you get a sphere rather than a cylinder
+
+Test6:
+------
+
+o Open recursivemain.scad
+o Compile (F5)
+o Verify that OpenSCAD won't hang or crash
+
+Test7:
+------
+
+o Open circularmain.scad
+o Compile (F5)
+o Verify that OpenSCAD won't hang or crash
+
+Test8:
+------
+
+o Open multiplemain.scad
+o Compile (F5) - verify that you get a sphere and a cube of approximately the same size
+o Edit multipleB.scad:
+  - cube(1.5*F(), center=true);
+  + cube(2.5*F(), center=true);
+o Reload and Compile (F4) - verify that the cube got larger
+
+Test9:
+------
+
+o Open includefrommodule.scad
+o Compile (F5) - Verify that you get a circular disc
+o Edit radius.scad: Change RADIUS
+o Compile (F5) - Verify that the disc changed size
+
+FIXME: Test circular include
