#	Author	: Sreedhar Sivakumaran
#	Purpose	: Build dtm modules for various targets.
#	Notes	:
#
#		Environment variable(s) to be pre-defined -  
#
#		1. DTMRCS - should be defined as the RCS library
#		   for the DTM files.
#
#		2. DTMSRC - should be defined as the directory 
#		   where all the dtm source files are to be available
#		   on being fetched from DTMRCS. 
#
#		3. DTMMOD - should be defined as the directory where
#		   the DTM module(s) should be built for the given node.
#
#		Associated files are makedtm and getdtm.
#		A typical dtm module generation sequence would be -
#
#		1. Fetch builddtm, makedtm, getdtm from the library 
#		   DTMRCS into the directory DTMSRC.
#
#		2. Execute getdtm in the directory DTMSRC - it
#		   will fetch all other files from DTMRCS.
#
#		3. At each target node, copy builddtm, makedtm and source
#		   files and execute builddtm in the DTMMOD directory, after
#		   chmod +x builddtm makedtm.
#
#		Other points -
#	
#		1. -DSUN is flag for sun machines. Similarly -DSGI, -DDEC and so on.
#		   However, flag is -DRS6000 for ibm machine.
#
#		2. For Cray, both libdtm.a and libdtmf77.a are built.
