This is the Perl distribution once.

INSTALLATION

once installation is straightforward. If your CPAN shell is
set up, you should just be able to do

    % cpan once

Download it, unpack it, then build it as per the usual:

    % perl Makefile.PL
    % make && make test

Then install it:

    % make install

DOCUMENTATION

once documentation is available as in POD. So you can do:

    % perldoc once

to read the documentation online with your favorite pager.
