+in SCons. Right now, it handles Builders, functions, construction
+variables, and Tools, but we expect it to get extended in the future.
In general, you can use any DocBook tag in the input, and this module
just adds processing various home-brew tags to try to make life a
Builder example:
- <builder name="VARIABLE">
+ <builder name="BUILDER">
<summary>
- This is the summary description of an SCons Tool.
+ This is the summary description of an SCons Builder.
It will get placed in the man page,
and in the appropriate User's Guide appendix.
The name of any builder may be interpolated
anywhere in the document by specifying the
- &b-VARIABLE;
+ &b-BUILDER;
element. It need not be on a line by itself.
Unlike normal XML, blank lines are significant in these
</summary>
</builder>
+Function example:
+
+ <scons_function name="FUNCTION">
+ <arguments>
+ (arg1, arg2, key=value)
+ </arguments>
+ <summary>
+ This is the summary description of an SCons function.
+ It will get placed in the man page,
+ and in the appropriate User's Guide appendix.
+ The name of any builder may be interpolated
+ anywhere in the document by specifying the
+ &f-FUNCTION;
+ element. It need not be on a line by itself.
+
+ Unlike normal XML, blank lines are significant in these
+ descriptions and serve to separate paragraphs.
+ They'll get replaced in DocBook output with appropriate tags
+ to indicate a new paragraph.
+
+ <example>
+ print "this is example code, it will be offset and indented"
+ </example>
+ </summary>
+ </scons_function>

Construction variable example:
<cvar name="VARIABLE">
Tool example:
- <tool name="VARIABLE">
+ <tool name="TOOL">
<summary>
This is the summary description of an SCons Tool.
