  77. <h4 class="subsubsection">6.3.7.2 Man Page Generation</h4>

  78. 

  79. <p>Because of user demand, in addition to full Texinfo manuals, man pages

  80. are provided which contain extracts from those manuals.  These man

  81. pages are generated from the Texinfo manuals using

  82. <samp>contrib/texi2pod.pl</samp> and <code>pod2man</code>.  (The man page for

  83. <code>g++</code>, <samp>cp/g++.1</samp>, just contains a &lsquo;<samp>.so</samp>&rsquo; reference

  84. to <samp>gcc.1</samp>, but all the other man pages are generated from

  85. Texinfo manuals.)

  86. </p>

  87. <p>Because many systems may not have the necessary tools installed to

  88. generate the man pages, they are only generated if the

  89. <samp>configure</samp> script detects that recent enough tools are

  90. installed, and the Makefiles allow generating man pages to fail

  91. without aborting the build.  Man pages are also included in release

  92. distributions.  They are generated in the source directory.

  93. </p>

  94. <p>Magic comments in Texinfo files starting &lsquo;<samp>@c man</samp>&rsquo; control what

  95. parts of a Texinfo file go into a man page.  Only a subset of Texinfo

  96. is supported by <samp>texi2pod.pl</samp>, and it may be necessary to add

  97. support for more Texinfo features to this script when generating new

  98. man pages.  To improve the man page output, some special Texinfo

  99. macros are provided in <samp>doc/include/gcc-common.texi</samp> which

  100. <samp>texi2pod.pl</samp> understands:

  101. </p>

  102. <dl compact="compact">

  103. <dt><code>@gcctabopt</code></dt>

  104. <dd><p>Use in the form &lsquo;<samp>@table @gcctabopt</samp>&rsquo; for tables of options,

  105. where for printed output the effect of &lsquo;<samp>@code</samp>&rsquo; is better than

  106. that of &lsquo;<samp>@option</samp>&rsquo; but for man page output a different effect is

  107. wanted.

  108. </p></dd>

  109. <dt><code>@gccoptlist</code></dt>

  110. <dd><p>Use for summary lists of options in manuals.

  111. </p></dd>

  112. <dt><code>@gol</code></dt>

  113. <dd><p>Use at the end of each line inside &lsquo;<samp>@gccoptlist</samp>&rsquo;.  This is

  114. necessary to avoid problems with differences in how the

  115. &lsquo;<samp>@gccoptlist</samp>&rsquo; macro is handled by different Texinfo formatters.

  116. </p></dd>

  117. </dl>

  118. 

  119. <p>FIXME: describe the <samp>texi2pod.pl</samp> input language and magic

  120. comments in more detail.
