Builtin Index Macros
====================
RefTeX by default recognizes the `\index' and `\glossary' macros
which are defined in the LaTeX core. It has also builtin support for
the re-implementations of `\index' in the `multind' and `index'
packages. However, since the different definitions of the `\index'
macro are incompatible, you will have to explicitly specify the index
style used. Note:Creating Index Entries, for information on how to
do that.
