=over

=item Guidelines for Module Creation

Do similar modules already exist in some form?, Try to design the new
module to be easy to extend and reuse, Some simple style guidelines, Select
what to export, Select a name for the module, Have you got it right?,
README and other Additional Files, A description of the
module/package/extension etc, A copyright notice - see below, Prerequisites
- what else you may need to have, How to build it - possible changes to
Makefile.PL etc, How to install it, Recent changes in this release,
especially incompatibilities, Changes / enhancements you plan to make in
the future, Adding a Copyright Notice, Give the module a
version/issue/release number, How to release and distribute a module, Take
care when changing a released module

=item Guidelines for Converting Perl 4 Library Scripts into Modules

There is no requirement to convert anything, Consider the implications,
Make the most of the opportunity, The pl2pm utility will get you started,
Adds the standard Module prologue lines, Converts package specifiers from '
to ::, Converts die(...) to croak(...), Several other minor changes

=item Guidelines for Reusing Application Code

Complete applications rarely belong in the Perl Module Library, Many
applications contain some perl code which could be reused, Break-out the
reusable code into one or more separate module files, Take the opportunity
to reconsider and redesign the interfaces, In some cases the 'application'
can then be reduced to a small
