Defining Label Environments
===========================
RefTeX can be configured to recognize additional labeled
environments and macros. This is done with the variable
`reftex-label-alist' (Note:Options (Defining Label Environments)).
If you are not familiar with Lisp, you can use the `custom' library to
configure this rather complex variable. To do this, use
M-x customize-variable <RET> reftex-label-alist <RET>
Here we will discuss a few examples, in order to make things clearer.
It can also be instructive to look at the constant
`reftex-label-alist-builtin' which contains the entries for all the
builtin environments and macros (Note:Builtin Label Environments).
