/***********************************************************************

      Epsilon editor emulation for Borland/Turbo Pascal IDE.

    This file contains a Turbo Editor Macro Language (TEML)
script which emulates the Epsilon programmer's editor in the Borland/Turbo
Pascal IDE.  A complete description of the TEML language and the Turbo
Editor Macro Compiler (TEMC) can be found in the file "TEMC.DOC".

    The TEMC compiler can be invoked from the DOS command line at
follows:
 
      temc [-c] epsilon.tem <IDE configuration file><.CMD><.TP>

The optional -c switch can also be specified as /c, and can appear in
any argument position on the command line. If you use this option,
any existing command table in your configuration file is thrown away
before the script file is merged with those already defined. The
configuration file extension must be specified as TEMC will modify both DOS
and Windows IDEs config files.  Specify .CMD or .TP extentions for Windows
or DOS IDE, respectively. If the .CMD file does not exist, it will be 
created. The .TP file must exist, or an error is displayed.

Most of the simple Epsilon commands have been fully implemented.  Most
of the complex command have been either partially implemented or not
implemented at all.  The TEML macros names correspond to the names in
the Espilon default macro set.  Below is a list of the commands that
have been fully or partially implemented.
