.SH DESCRIPTION
.IX Header "DESCRIPTION"
This module is used by Schmorp's modules during configuration stage to
test the installed perl for compatibility with his modules.
.PP
It's not, at this stage, meant as a tool for other module authors,
although in principle nothing prevents them from subscribing to the same
ideas.
.PP
See the \fIMakefile.PL\fR in Coro or AnyEvent for usage examples.

.el .IP \f(CWPERL_CANARY_STABILITY_NOPROMPT=1\fR 4

Do not prompt the user on alert messages.

Disable use of colour.

.el .IP \f(CWPERL_CANARY_STABILITY_COLOUR=1\fR 4
.IX Item "PERL_CANARY_STABILITY_COLOUR=1"
Force use of colour.

.el .IP \f(CWPERL_CANARY_STABILITY_DISABLE=1\fR 4
.IX Item "PERL_CANARY_STABILITY_DISABLE=1"
Disable this modules functionality completely.
.ie n .IP """AUTOMATED_TESTING=1""" 4
.el .IP \f(CWAUTOMATED_TESTING=1\fR 4
.IX Item "AUTOMATED_TESTING=1"
When this variable is set to a true value and the perl minimum version
requirement is not met, the module will exit, which should skip testing
under automated testing environments.
.Sp
This is done to avoid false failure or success reports when the chances of
success are already quite low and the failures are not supported by the
author.
