<para>The <parameter>man.string.subst.map</parameter> parameter
84
contains <link linkend="map">a map</link> that specifies a set of
85
string substitutions to perform over the entire roff source for each
86
man page, either just before generating final man-page output (that
87
is, before writing man-page files to disk) or, if the value of the
88
<parameter>man.charmap.enabled</parameter> parameter is non-zero,
89
before applying the roff character map.</para>
91
<para>You can use <parameter>man.string.subst.map</parameter> as a
92
“lightweight” character map to perform “essential” substitutions --
93
that is, substitutions that are <emphasis>always</emphasis> performed,
94
even if the value of the <parameter>man.charmap.enabled</parameter>
95
parameter is zero. For example, you can use it to replace quotation
96
marks or other special characters that are generated by the DocBook
97
XSL stylesheets for a particular locale setting (as opposed to those
98
characters that are actually in source XML documents), or to replace
99
any special characters that may be automatically generated by a
100
particular customization of the DocBook XSL stylesheets.</para>
103
<para>Do you not change value of the
104
<parameter>man.string.subst.map</parameter> parameter unless you are
105
sure what you are doing. First consider adding your
106
string-substitution mappings to either or both of the following
110
<term><parameter>man.string.subst.map.local.pre</parameter></term>
111
<listitem><para>applied before
112
<parameter>man.string.subst.map</parameter></para></listitem>
115
<term><parameter>man.string.subst.map.local.post</parameter></term>
116
<listitem><para>applied after
117
<parameter>man.string.subst.map</parameter></para></listitem>
120
By default, both of those parameters contain no
121
string substitutions. They are intended as a means for you to
122
specify your own local string-substitution mappings.</para>
124
<para>If you remove any of default mappings from the value of the
125
<parameter>man.string.subst.map</parameter> parameter, you are
126
likely to end up with broken output. And be very careful about adding
127
anything to it; it’s used for doing string substitution over the
128
entire roff source of each man page – it causes target strings to be
129
replaced in roff requests and escapes, not just in the visible
130
contents of the page.</para>
134
<refsection xml:id="map">
136
<title>Contents of the substitution map</title>
138
<para>The string-substitution map contains one or more
139
<tag>ss:substitution</tag> elements, each of which has two
143
<term>oldstring</term>
145
<simpara>string to replace</simpara>
149
<term>newstring</term>
151
<simpara>string with which to replace <tag

It may also include XML comments (that is, delimited with
157
"<literal><!--</literal>" and "<literal>--></literal>").
