Index of RCL commands (incomplete):
A sample RCL script that is used to pre-process the RSF generated with cparse
for Rigi has been written by JohannesMartin. The RCL script is generic and works for most C programs. He also used the script (with slight modifications) to look at web site structures.
Note that the preprocessing takes away detail and creates a specific structure in the graph. For example, all of the standard library is filtered out. You can use the script as a starting point and modify it to suit your own, specific needs.
