The file |ltxdoc.cfg| is used to customise some aspects of the behaviour of the ltxdoc class; this class is used to typeset the documented code in the |.dtx| files. If this file is present then it is read in at the beginning of the file |ltxdoc.cls|.
As this file is read before the article class is loaded, you may pass options to article. For example the following line might be added to |ltxdoc.cfg| to format the documentation for A4 paper instead of the default US letter paper size.
||You should note however, that even if paper size options are specified, the ltxdoc class always sets the || parameter to 355 pt, to enable 72 columns of text to appear in the verbatim code listings. If you really need to over-ride this you could use:
||To set the || to your desired value at the end of the ltxdoc class.
By default, most of the |.dtx| documented code files in the distribution will produce a `description' section followed by full source listing of the package. If you wish to suppress the source listings you may add the following line to |ltxdoc.cfg|
||
The documentation of the ltxdoc package, which may be typeset from the file |ltxdoc.dtx|, contains more examples of the use of this configuration file.
