36 =head1 NAME
38 fix-perl-path.PL - A script to correct the shebang line to match the current platform
40 =head1 SYNOPSIS
42 =head2 BASIC USAGE
44 perl fix-perl-path.PL /absolute/path/to/foo
46 =head1 DESCRIPTION
48 This script should be run from the base of the directory
49 structure which contains the file(s) that need the
50 shebang line corrected. It will recurse through all
51 directories below the one called from and modify all
52 .pl files.
54 =head2 fixshebang
56 This sub will recurse through a given directory and its subdirectories checking for the existence of a shebang
57 line in .pl files and replacing it with the correct line for the current OS if needed. It should be called
58 in a manner similar to 'fixshebang (foodir)' but may be supplied with any directory.
