1. command-line source browsing tool. cgvg is a pair of Perl scripts ("cg" and "vg") which are meant to assist a programmer in doing command-line source browsing. The idea is you can easily search for keywords in the code, and jump to the file and line where a match is found. Used with ctags(1), this can really help with jumping around and following code. Some features include a human-readable output, coloring, bolding (and alternate bolding), and just sheer convenience for a programmer. cgvg uses the Perl internal find and does it's own searching, rather than being a wrapper for UNIX find(1) and grep(1). There is a ~/.cgvgrc file for per-user configuration, and some nice features like coloring, and multiple log files. From Debian 3.0r0 APT
