kiss' help output will now include all executables found in $PATH which begin with kiss-*. A comment string is optionally usable via setting the second line of the script to a string. Example: ... This also means that 'kiss <script name>' is also possible now. If I have a script in my $PATH called kiss-depends, I can now use it via kiss with 'kiss depends'.
