149 | =head1 NAME | |
150 | ||
151 | mkppport - distribute ppport.h among extensions | |
152 | ||
153 | =head1 SYNOPSIS | |
154 | ||
155 | mkppport [B<--list>=I<file>] [B<--clean>] | |
156 | ||
157 | =head1 DESCRIPTION | |
158 | ||
159 | B<mkppport> generates a I<ppport.h> file using Devel::PPPort | |
160 | and distributes it to the various extension directories that | |
161 | need it to build. | |
162 | ||
163 | =head1 OPTIONS | |
164 | ||
165 | =over 4 | |
166 | ||
167 | =item B<--list>=I<file> | |
168 | ||
169 | Name of the file that holds the list of extension directories | |
170 | that I<ppport.h> should be distributed to. | |
171 | This defaults to I<mkppport.lst> in the same directory as this | |
172 | script. | |
173 | ||
174 | =item B<--clean> | |
175 | ||
176 | Run with this option to clean out all distributed I<ppport.h> files. | |
