   =head1 NAME
   
   filecompare.pl - script used to help probe and compare file statistics
   
   =head1 SYNOPSIS
   
   filecompare.pl [ options ... ] [FILE1] [FILE2] [ restrictions ... ]
   
   or
   
   filecompare.pl [ options ... ] [DIR1] [DIR2] [ restrictions ... ]
   
   Restrictions: a list of space separated values (after the file/dir names)
   can restrict the comparison.
   These values can be: existence, cvstime, age, md5sum, size, lines,
   and/or diffs.
   
   Options (before file/dir names):
   
    -p show all files that have the same comparison
   
    -n show all files that have different comparisons
   
    -a show all files (with comparisons)
   
    -q only show file names (based on first file/dir)
   
    -v verbose mode (default)
   
   =head1 DESCRIPTION
   
   filecompare.pl can work in two modes: file comparison mode, or directory
   comparison mode.
   
   Comparisons can be a function of:
   * existence similarity
   * cvs time similarity (first argument treated as CVS source)
   * age similarity (modification time)
   * md5sum similarity
   * size similarity (bytes)
   * line count difference
   * number of different lines
   
   filecompare.pl integrates smoothly with the LPML installation language
   (linux packaging markup language).  filecompare.pl is a tool that can
   be used for safe CVS source-to-target installations.

   filecompare.pl integrates smoothly with the LPML installation language
   (linux packaging markup language).  filecompare.pl is a tool that can
   be used for safe CVS source-to-target installations.
   
   The unique identifier is considered to be the file name(s) independent
   of the directory path.
