You can do a lot of nice stuff just parsing the cvsweb. For example,
here's a very basic script for showing supported branches:
#!/usr/bin/perl -w
use strict;
use LWP::Simple;
print "Supported branches of FreeBSD:\n\n";
my @content = split /\n/, get("http://www.freebsd.org/cgi/cvsweb.cgi/~checkout~/www/en/security/security.sgml");
die "Couldn't get url!" unless @content;
my $line = shift @content;
do { $line = shift @content; } until ($line =~ /name="supported-branches"/);
do { $line = shift @content; } until ($line =~ /table class="tblbasic"/);
while ($line = shift @content) {
last if $line =~ /\<\/table\>/;
if ($line =~ /\<t[hd]\>/) {
$line =~ s/<[^>]*>//g;
$line =~ s/^\s*//;
printf "%-20s", $line;
}
print "\n" if $line =~ /\<\/tr\>/;
}
