Initial revision

#
# Commonrules to build idb's and images for an ism
#
#
# For an ism that doesn't have a rawidb idb
# set LIDBJOINFLAGS to -m
# In this case a zero length RAWIDB is required
#
#
# Targets:
#	buildimages - make real images (an individual image can also be made)
#	buildidbs - makes an external idb
#		   these idb(s) are the exported ones - the image names
#		   must correspond to the public exported names that the
#		   ism has published (and are used in the product
#		   defining spec files).
#		   The idb also must have full path names to the location
#		   of the objects
#	buildism - old name for buildidbs
#	version - create a version file
#	startversion - create a version number in $(WORKAREA)/.version_number
#		(and alpha number in $(WORKAREA)/.alpha_number
#
# Before including this file the following should be set:
#	ALLIMAGES - names of images to be made - must correspond to
#		product name(s) in spec file
#	SPEC - spec file name
#	RAWIDB - rawidb file name
#	SRCIDB - src/checked in idb file name
#
# Macros you may wish to set
#	BUILDER - (to 1 if project build, to 2 if build group build) 
#	TREE_ID - to an integer 1-9 to distinguish parallel OS efforts
#		  targeted to new hardware.
#		  It will default to the value of TREE_ID found in 
#		  $(IVDEPTH)/make/releasedefs.
#	PATCH_RELEASE - if creating a patch release (will default to first eight
#		  digits of $(WORKAREA)/.version_number)
#	PATCH_NUM - patch number (sequences patch releases)
#
# Note that macros ALLIMAGES, SPEC, RAWIDB, and SRCIDB need only be set
#	in the build/Makefile. Typically, one just uses the settings as 
#	provided via the ism template for the build/Makefile.
#
