Perl scripts linked into /usr/local/bin or anyother directory needs
to use FindBin qw($RealBin) instead of just FindBin qw($Bin). Realpath
will find the absolute path to where the script actually lives and the
pm directory that holds the perl modules.
We were using md5_hex to generate a unique file id from a full path
filename. Changed this to use the file device and inode id instead.
Should still provide unique file ids and the file names are shorter
too.
Fixes#29
Changed all header file once include variables to follow the same naming
convention and not start with any underscores. Also deleted old
incorrect copyright notices. Also removed $Id: tags from all files.
Fixes#14. Fixes#22.
Fiexed the shell detection logic by not trying to. Changed the
install_user script to just print the add TRICK_HOME to the
PATH for both types of shells.
