=====================
NOTES and CHANGE-LOG:
=====================
NOTE:  you can revise your CONFIG-FILE, ~/.linesrc, for LLPROGRAMS (dirs for report-scripts), for your Date-Format preferences, etc;
NOTE:  if the finding of llexec doesn't work, just hard-code it as something like:  LLEXEC=/usr/bin/llexec

DEBUGGING a Lines-program in batch-mode:
for syntax-errors you'll get a perfectly good msg,  however for undefined function or runtime-errors you'll get endless repetition which must be interupted;  
however this bug in lifelines-3.0.50 may be fixed in newer versions?

2010-09-03:  improved the finding of the Lifelines llexec executable, to be foolproof on any Nix system;  was assuming it in a /usr* directory and this script not;
