VERSION

return
pod2usage(

$ERROR

DESCRIPTION
This is a drop-in replacement for Pod::Usage pod2usage
that returns the exit value instead of calling exit.
RATIONALE
Testing that your command-line script works is a good thing. It's a lot easier to test a module, so writing your command-line script as a module ("modulino") makes it easier to test.
Unfortunately, Pod::Usage automatically calls exit
, which again makes it harder to test your script. There is a way to prevent Pod::Usage from exiting, but it makes using Pod::Usage a lot less convenient.
This module provides a drop-in pod2usage
replacement that returns the exit code instead of exiting, so that you can easily test your script while using Pod::Usage.
FUNCTIONS
pod2usage
See Pod::Usage for documentation. Returns the exit code instead of calling exit().
