=head1 SYNOPSIS |
87
|
|
|
|
|
|
|
|
88
|
|
|
|
|
|
|
On different systems, different approaches are needed to detect the number of cores for that machine. |
89
|
|
|
|
|
|
|
|
90
|
|
|
|
|
|
|
This Module is a wrapper around these different approaches. |
91
|
|
|
|
|
|
|
|
92
|
|
|
|
|
|
|
=head1 USAGE |
93
|
|
|
|
|
|
|
|
94
|
|
|
|
|
|
|
This module will install one executable, C<<< mcores >>>, in your bin. |
95
|
|
|
|
|
|
|
|
96
|
|
|
|
|
|
|
It is really simple and straightforward: |
97
|
|
|
|
|
|
|
|
98
|
|
|
|
|
|
|
usage: mcores [-?i] [long options...] |
99
|
|
|
|
|
|
|
-? --usage --help Prints this usage information. |
100
|
|
|
|
|
|
|
-i --add-one add one to the number of cores (useful in scripts) |
101

|
=head1 WARNING |
103
|
|
|
|
|
|
|
|
104
|
|
|
|
|
|
|
Some questions with Dist::Zilla are still open, and although this module attempts to load L<Mouse> instead of L<Moose>, |
105
|
|
|
|
|
|
|
unfortuantely, however, B<both> modules are installed as prerequisites. This will change soon. |
