The `"include" directive`__ +has a special syntax for these standard definition files, angle +brackets around the file name:: + + .. include:: <filename.txt> + +__ directives.html#include + +The individual data files are stored with the Docutils source code in +the "docutils" package, in the ``docutils/parsers/rst/include`` +directory. + + +Substitution Definitions +======================== + +Many of the standard definition files contain sets of `substitution +definitions`__, which can be used in documents via `substitution +references`__. For example, the copyright symbol is defined in +``isonum.txt`` as "copy":: + + .. include:: <isonum.txt> + + Copyright |copy| 2003 by John Q. Public, all rights reserved. + +__ restructuredtext.html#substitution-definitions +__ restructuredtext.html#substitution-references + +Individual substitution definitions can also be copied from definition +files and pasted into documents. This has two advantages: it removes +dependencies, and it saves processing of unused definitions. However, +multiple substitution definitions add clutter to the document. + +Substitution references require separation from the surrounding text +with whitespace or punctuation. To use a substitution without +intervening whitespace, you can use the disappearing-whitespace escape +sequence, backslash-space:: + + .. include:: isonum.txt + + Copyright |copy| 2003, BogusMegaCorp\ |trade|. + +Custom substitution definitions may use the `"unicode" directive`__. +Whitespace is ignored and removed, effectively sqeezing together the +text:: + + .. |copy| unicode:: U+000A9 ..
