Module::Build::Platform::MacOS(3pm)			 Perl Programmers Reference Guide		       Module::Build::Platform::MacOS(3pm)

NAME

       Module::Build::Platform::MacOS - Builder class for MacOS platforms

DESCRIPTION

       The sole purpose of this module is to inherit from "Module::Build::Base" and override a few methods.  Please see Module::Build for the
       docs.

   Overridden Methods
       new()
	   MacPerl doesn't define $Config{sitelib} or $Config{sitearch} for some reason, but $Config{installsitelib} and $Config{installsitearch}
	   are there.  So we copy the install variables to the other location

       make_executable()
	   On MacOS we set the file type and creator to MacPerl so it will run with a double-click.

       dispatch()
	   Because there's no easy way to say "./Build test" on MacOS, if dispatch is called with no arguments and no @ARGV a dialog box will pop
	   up asking what action to take and any extra arguments.

	   Default action is "test".

       ACTION_realclean()
	   Need to unlock the Build program before deleting.
