NAME

       Version::Next - increment module version numbers simply and correctly

VERSION

       version 0.002

SYNOPSIS

	  use Version::Next;

	  my $new_version = next_version( $old_version );

DESCRIPTION

       This module provides a simple, correct way to increment a Perl module version number.  It does not attempt to guess what the original
       version number author intended, it simply increments in the smallest possible fashion.  Decimals are incremented like an odometer.  Dotted
       decimals are incremented piecewise and presented in a standardized way.

       If more complex version manipulation is necessary, you may wish to consider Perl::Version.

USAGE

       This module uses Sub::Exporter for optional exporting.  Nothing is exported by default.

   "next_version"
	  my $new_version = next_version( $old_version );

       Given a string, this function make the smallest logical increment and returns it.  The input string is very minimally checked that it
       resembles a version number.  Given "undef", the function returns 0.

       Decimal versions are incremented like an odometer, preserving the original number of decimal places.  If an underscore is present
       (indicating an "alpha" version), its relative position is preserved.  Examples:

	  0.001    ->	0.002
	  0.999    ->	1.000
	  0.1229   ->	0.1230
	  0.12_34  ->	0.12_35
	  0.12_99  ->	0.13_00

       Dotted-decimal versions have the least significant element incremented by one.  If the result exceeds 999, the element resets to 0 and the
       next most significant element is incremented, and so on.  Any leading zero padding is removed.  Examples:

	 v1.2.3     ->	v1.2.4
	 v1.2.999   ->	v1.3.0
	 v1.999.999 ->	v2.0.0
	 v1.2.3_4   ->	v1.2.3_5
	 v1.2.3_999 ->	v1.2.4_0
