CPANPLUS::Shell::Default::Plugins::Source(3)		User Contributed Perl Documentation	      CPANPLUS::Shell::Default::Plugins::Source(3)

NAME

       CPANPLUS::Shell::Default::Plugins::Source - read in CPANPLUS commands

SYNOPSIS

	   CPAN Terminal> /source /tmp/list_of_commands /tmp/more_commands

DESCRIPTION

       This is a "CPANPLUS::Shell::Default" plugin that works just like your unix shells source(1) command; it reads in a file that has commands
       in it to execute, and then executes them.

       A sample file might look like this:

	   # first, update all the source files
	   x --update_source

	   # find all of my modules that are on the CPAN
	   # test them, and store the error log
	   a ^KANE$'
	   t *
	   p /home/kane/cpan-autotest/log

	   # and inform us we're good to go
	   ! print "Autotest complete, log stored; please enter your commands!"

       Note how empty lines, and lines starting with a '#' are being skipped in the execution.
