=head1 SYNOPSIS

`prove -PTestRail='apiurl=http://some.testlink.install/,user=someUser,password=somePassword,project=TestProject,run=TestRun,plan=TestPlan,configs=Config1:Config2:Config3,version=0.014' sometest.t`

=head1 DESCRIPTION

Prove plugin to upload test results to TestRail installations.

Accepts input in the standard Prove plugin fashion (-Ppluginname='key=value,key=value,key=value...'), but will also parse a config file.
When fed in prove plugin style, key=value input is expected.

If \$HOME/.testrailrc exists, it will be parsed for any of these values in a newline separated key=value list.  Example:

    apiurl=http://some.testrail.install
    user=someGuy
    password=superS3cret
    project=TestProject
    run=TestRun
    plan=GosPlan
    configs=config1:config2:config3: ... :configN
    version=xx.xx.xx.xx
    case_per_ok=0
    step_results=sr_sys_name

Note that passing configurations as filters for runs inside of plans are separated by colons.
Values passed in via query string will override values in \$HOME/.testrailrc.
If your system has no concept of user homes, it will look in the current directory for .testrailrc.

=head1 OVERRIDDEN METHODS

=head2 load(parser)

Shoves the arguments passed to the prove plugin into $ENV so that Test::Rail::Parser can get at them.
Not the most elegant solution, but I see no other clear path to get those variables downrange to it's constructor.
