NAME

       File::Compare - Compare files or filehandles

SYNOPSIS

	       use File::Compare;

	       if (compare("file1","file2") == 0) {
		   print "They're equal
";
	       }

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]} )

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.

NAME

       Number::Compare - numeric comparisons

SYNOPSIS

	Number::Compare->new(">1Ki")->test(1025); # is 1025 > 1024

	my $c = Number::Compare->new(">1M");
	$c->(1_200_000);			  # slightly terser invocation

DESCRIPTION

       Number::Compare compiles a simple comparison to an anonymous subroutine, which you can call with a value to be tested again.

       Now this would be very pointless, if Number::Compare didn't understand magnitudes.

       The target value may use magnitudes of kilobytes ("k", "ki"), megabytes ("m", "mi"), or gigabytes ("g", "gi").  Those suffixed with an "i"
       use the appropriate 2**n version in accordance with the IEC standard: http://physics.nist.gov/cuu/Units/binary.html

METHODS

   ->new( $test )
       Returns a new object that compares the specified test.

   ->test( $value )
       A longhanded version of $compare->( $value ).  Predates blessed subroutine reference implementation.

   ->parse_to_perl( $test )
       Returns a perl code fragment equivalent to the test.
