<h4 class="subsubsection">6.3.7.2 Man Page Generation</h4>
|
|
|
|
<p>Because of user demand, in addition to full Texinfo manuals, man pages
|
|
are provided which contain extracts from those manuals. These man
|
|
pages are generated from the Texinfo manuals using
|
|
<samp>contrib/texi2pod.pl</samp> and <code>pod2man</code>. (The man page for
|
|
<code>g++</code>, <samp>cp/g++.1</samp>, just contains a ‘<samp>.so</samp>’ reference
|
|
to <samp>gcc.1</samp>, but all the other man pages are generated from
|
|
Texinfo manuals.)
|
|
</p>
|
|
<p>Because many systems may not have the necessary tools installed to
|
|
generate the man pages, they are only generated if the
|
|
<samp>configure</samp> script detects that recent enough tools are
|
|
installed, and the Makefiles allow generating man pages to fail
|
|
without aborting the build. Man pages are also included in release
|
|
distributions. They are generated in the source directory.
|
|
</p>
|
|
<p>Magic comments in Texinfo files starting ‘<samp>@c man</samp>’ control what
|
|
parts of a Texinfo file go into a man page. Only a subset of Texinfo
|
|
is supported by <samp>texi2pod.pl</samp>, and it may be necessary to add
|
|
support for more Texinfo features to this script when generating new
|
|
man pages. To improve the man page output, some special Texinfo
|
|
macros are provided in <samp>doc/include/gcc-common.texi</samp> which
|
|
<samp>texi2pod.pl</samp> understands:
|
|
</p>
|
|
<dl compact="compact">
|
|
<dt><code>@gcctabopt</code></dt>
|
|
<dd><p>Use in the form ‘<samp>@table @gcctabopt</samp>’ for tables of options,
|
|
where for printed output the effect of ‘<samp>@code</samp>’ is better than
|
|
that of ‘<samp>@option</samp>’ but for man page output a different effect is
|
|
wanted.
|
|
</p></dd>
|
|
<dt><code>@gccoptlist</code></dt>
|
|
<dd><p>Use for summary lists of options in manuals.
|
|
</p></dd>
|
|
<dt><code>@gol</code></dt>
|
|
<dd><p>Use at the end of each line inside ‘<samp>@gccoptlist</samp>’. This is
|
|
necessary to avoid problems with differences in how the
|
|
‘<samp>@gccoptlist</samp>’ macro is handled by different Texinfo formatters.
|
|
</p></dd>
|
|
</dl>
|
|
|
|
<p>FIXME: describe the <samp>texi2pod.pl</samp> input language and magic
|
|
comments in more detail.
