librm.so.2.0.1
--------------

This library contains the server frontend, a state stack, some string
functions and some GUI extensions. 

Lots of changes since 1.1.0:

- dropped the multiple search interface
- added state stack (could have implemented it in 20 lines of 
  TCL-code, though ...)
- the search engine was replaced by a server frontend that talks to
  a separate server process
- split up bloated glue.c code into glue, server frontend and state stack
  parts

When 'wish' is linked with this library (e.g. using the
'load' command), the following new Tcl-commands become available:

from glue.o:
-----------

rm_expand_and_show

  expands all visible search results

rm_fill_listbox <# of lines>

rm_issubset <set> <subset>

  duh.

rm_subset_subtract <set> <subset>
