=head1 DESCRIPTION
|
||
|
|
|
||
|
|
This program runs a Sphinx program I<PROGRAM>, reads a template file
|
||
|
|
from standard input, and writes a manual page in L<man(7)> format to
|
||
|
|
standard output.
|
||
|
|
|
||
|
|
The template file is a manual page in L<man(7)> format, containing a
|
||
|
|
comment line of the form:
|
||
|
|
|
||
|
|
.\" ### ARGUMENTS ###
|
||
|
|
|
||
|
|
Which will be replaced in the output with the arguments and their
|
||
|
|
descriptions from I<PROGRAM>.
