     Modules: Creation, Use, and Abuse

     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



                                                                       Page 25

          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

     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

     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

     Strategies for storing Callback Context Information
          1. Ignore the problem - Allow only 1 callback, 2. Create a sequence
          of callbacks - hard wired limit, 3. Use a parameter to map to the
          Perl callback
