Subject: Add the _abort(), _notify() and _skip() diagnostics methods
X-Git-Tag: v0.08~15
X-Git-Url: http://git.vpit.fr/?p=perl%2Fmodules%2FCPANPLUS-Dist-Gentoo.git;a=commitdiff_plain;h=a631ba02aecb81e70e9c60d6d37ce554c7f707c2

Add the _abort(), _notify() and _skip() diagnostics methods

And make $FAIL->($msg) call ->_abort($msg).
CPANPLUS::Error doesn't pollute our namespace anymore.
