-=head1 NAME
-
-testcmp -- compare two files line-by-line
-
-=head1 SYNOPSIS
-
- $is_diff = testcmp($file1, $file2);
-
-or
-
- $is_diff = testcmp({-cmplines => \&mycmp}, $file1, $file2);
-
-=head2 DESCRIPTION
-
-Compare two text files line-by-line and return 0 if they are the
-same, 1 if they differ. Each of $file1 and $file2 may be a filenames,
-or a filehandles (in which case it must already be open for reading).
-
-If the first argument is a hashref, then the B<-cmplines> key in the
-hash may have a subroutine reference as its corresponding value.
-The referenced user-defined subroutine should be a line-comparator
-function that takes two pre-chomped text-lines as its arguments
-(the first is from $file1 and the second is from $file2). It should
-return 0 if it considers the two lines equivalent, and non-zero
-otherwise.
