This script acts as a handy interface to the CPAN testers service, allowing you to quickly check pass/fail rates for a particular release.

It fetches YAMLJSON and performs HTTP caching, so probably puts less stress on the CPAN testers servers than a hit from a browser.

Usage:
	cpan-testers Example-Distribution
	cpan-testers -v0.001 Example-Distribution
	cpan-testers -ov0.001 Example-Distribution
	cpan-testers -s Example-Distribution

Options:
	--version=V, -vV   Show results for particular release version.
	--os, -o           Break down by operating system.
	--summary, -s      Show summary for all versions
	                   (excludes "--version" and "--os" options).
	--stable, -S       Hide dev versions (excludes "--version").

Requires:

Update: switched from retrieving YAML to retrieving JSON. The YAML files seem a bit smaller, but JSON parsing seems more reliable, and the JSON files served by the CPAN Testers site seem to have more cache-friendly headers.
