151 | =head1 NAME | |
152 | ||
153 | mkppport - distribute ppport.h among extensions | |
154 | ||
155 | =head1 SYNOPSIS | |
156 | ||
157 | mkppport [B<--list>=I<file>] [B<--clean>] | |
158 | ||
159 | =head1 DESCRIPTION | |
160 | ||
161 | B<mkppport> generates a I<ppport.h> file using Devel::PPPort | |
162 | and distributes it to the various extension directories that | |
3bdc51af DD |
163 | need it to build. On certain Win32 builds, this script is not |
164 | used and an alternative mechanism is used to create I<ppport.h>. | |
42e07562 MHM |
165 | |
166 | =head1 OPTIONS | |
167 | ||
168 | =over 4 | |
169 | ||
170 | =item B<--list>=I<file> | |
171 | ||
172 | Name of the file that holds the list of extension directories | |
173 | that I<ppport.h> should be distributed to. | |
174 | This defaults to I<mkppport.lst> in the same directory as this | |
175 | script. | |
176 | ||
177 | =item B<--clean> | |
178 | ||
179 | Run with this option to clean out all distributed I<ppport.h> files. | |
