NAME ^

Perinci::Examples - Example modules containing metadata and various example functions

VERSION ^

This document describes version 0.32 of Perinci::Examples (from Perl distribution Perinci-Examples), released on 2014-09-11.

SYNOPSIS ^

 use Perinci::Examples qw(delay);
 delay();

DESCRIPTION ^

This module and its submodules contain an odd mix of various functions, variables, and other code entities, along with their Rinci metadata. Mostly used for testing Rinci specification and the various Perinci modules.

Example scripts are put in a separate distribution (see Perinci::Examples::Bin) to make dependencies for this distribution minimal (e.g. not depending on Perinci::CmdLine) since this example module(s) are usually used in the tests of other modules.
