=head1 NAME
Module::Starter::PBP - Create a module as recommended in "Perl Best Practices"
=head1 VERSION
This document describes Module::Starter::PBP version 0.0.3
=head1 SYNOPSIS
# In your ~/.module-starter/config file...
author: <Your Name>
email: <your@email.addr>
plugins: Module::Starter::PBP
template_dir: </some/absolute/path/name>
# Then on the command-line...
> module-starter --module=Your::New::Module
# Or, if you're lazy and happy to go with
# the recommendations in "Perl Best Practices"...
> perl -MModule::Starter::PBP=setup
=head1 DESCRIPTION
This module implements a simple approach to creating modules and their support
files, based on the Module::Starter approach. Module::Starter needs to be
installed before this module can be used.
When used as a Module::Starter plugin, this module allows you to specify a
simple directory of templates which are filled in with module-specific
information, and thereafter form the basis of your new module.
The default templates that this module initially provides are based on
the recommendations in the book "Perl Best Practices".
=head1 INTERFACE
Thsi module simply acts as a plugin for Module::Starter. So it uses the same
command-line interface as that module.
The template files it is to use are specified in your Module::Starter
C<config> file, by adding a C<template_dir> configuration variable that
gives the full path name of the directory in which you want to put
the templates.
The easiest way to set up this C<config> file, the associated directory, and
the necessary template files is to type:
> perl -MModule::Starter::PBP=setup
on the command line. You will then be asked for your name, email address, and
the full path name of the directory where you want to keep the templates,
after which they will be created and installed.
Then you can create a new module by typing:
> module-starter --module=Your::New::Module
=head2 Template format
The templates are plain files named:
Build.PL
Makefile.PL
README
Changes
Module.pm
t/whatever_you_like.t
The C<Module.pm> file is the template for the C<.pm> file for your module. Any
files in the C<t/> subdirectory become the templates for the testing files of
your module. All the remaining files are templates for the ditribution files
of the same names.
In those files, the following placeholders are replaced by the appropriate
information specific to the file:
=over
=item <AUTHOR>
The nominated author. Taken from the C<author> setting in
your Module::Starter C<config> file.
=item <BUILD INSTRUCTIONS>
Makefile or Module::Build instructions. Computed automatically according to
the C<builder> setting in your Module::Starter C<config> file.
=item <DATE>
The current date (as returned by C<localtime>). Computed automagically
=item <DISTRO>
The name of the complete module distribution. Computed automatically from the
name of the module.
=item <EMAIL>
Where to send feedback. Taken from the C<email> setting in
your Module::Starter C<config> file.
=item <LICENSE>
The licence under which the module is released. Taken from the C<license>
setting in your Module::Starter C<config> file.
=item <MAIN MODULE>
The name of the main module of the distribution.
=item <MAIN PM FILE>
The name of the C<.pm> file for the main module.
=item <MODULE NAME>
The name of the current module being created within the distribution.
=item <RT NAME>
The name to use for bug reports to the RT system.
That is:
Please report any bugs or feature requests to
bug-<RT NAME>@rt.cpan.org>
=item <YEAR>
The current year. Computed automatically
=back
=head1 DIAGNOSTICS
=over
=item C<< Can't find directory that holds Module::Starter::PBP templates >>
You did not tell Module::Starter::PBP where your templates are stored.
You need a 'template_dir' specification. Typically this would go in
your ~/.module-starter/config file. Something like:
template_dir: /users/you/.module-starter/Templates
=item C<< Can't access Module::Starter::PBP template directory >>
You specified a 'template_dir', but the path didn't lead to a readable
directory.
=item C<< The template: %s isn't in the template directory (%s) >>
One of the required templates:
was missing from the template directory you specified.
=item C<< The template: %s isn't readable in the template directory (%s) >>
One of the templates in the template directory you specified was not readable.
=item C<< Unknown placeholder <%s> in %s >>
One of the templates in the template directory contained a replacement item
that wasn't a known piece of information.
=back
=head1 CONFIGURATION AND ENVIRONMENT

=head1 DEPENDENCIES
Requires the C<Module::Starter> module.
=head1 INCOMPATIBILITIES
None reported.

The README is used to introduce the module and provide instructions on
how to install the module, any machine dependencies it may have (for
example C compilers and installed libraries) and any other information
that should be understood before the module is installed.
A README file is required for CPAN modules since CPAN extracts the
README file from a module distribution so that people browsing the
archive can use it get an idea of the modules uses. It is usually a
good idea to provide version information here so that people can
decide whether fixes for the module are worth downloading.
