We will do this for the other popular third party tools befor final release, and
 we'll
document it as well.  To add support for MPC, you can copy TLMPLABC.INI to
 TLMPC.INI,
and MPLAB.MTC to MPC.MTC.

Edit TLMPC.INI  to

[Language_Suite]
LanguageSuite=Byte Craft
DefaultFilename=default.bc
Target=HEX
Library=LIB
Source=C
Header=H;INC
Output=LST;ERR;MAP;HEX
Debug=COD
MTC_Files=mpc


Note the last line points to the MPC.INI  MPLAB will search for TL*.INI files
 for other
tools.

Look at MPC.INI.  It contains info on all the command line switches.  You can
 probably
figure them out to get it working since MPLAB-C is derived from MPC.
