-=head1 NAME
-
-File::Compare - Compare files or filehandles
-
-=head1 SYNOPSIS
-
- use File::Compare;
-
- if (compare("file1","file2") == 0) {
- print "They're equal\n";
- }
-
-=head1 DESCRIPTION
-
-The File::Compare::compare function compares the contents of two
-sources, each of which can be a file or a file handle. It is exported
-from File::Compare by default.
-
-File::Compare::cmp is a synonym for File::Compare::compare. It is
-exported from File::Compare only by request.
-
-File::Compare::compare_text does a line by line comparison of the two
-files. It stops as soon as a difference is detected. compare_text()
-accepts an optional third argument: This must be a CODE reference to
-a line comparison function, which returns 0 when both lines are considered
-equal. For example:
-
- compare_text($file1, $file2)
-
-is basically equivalent to
-
- compare_text($file1, $file2, sub {$_[0] ne $_[1]} )
-
-=head1 RETURN
-
-File::Compare::compare and its sibling functions return 0 if the files
-are equal, 1 if the files are unequal, or -1 if an error was encountered.
-
-=head1 AUTHOR
-
-File::Compare was written by Nick Ing-Simmons.
-Its original documentation was written by Chip Salzenberg.
