######################## How to define new 'features' #######################
#
# One defines new 'features' exactly like devices (see devs.mak for details).
# For example, one would define a feature abc by adding the following to
# gs.mak:
#
#	abc_=abc1.$(OBJ) ...
#	abc.dev: $(GS_MAK) $(ECHOGS_XE) $(abc_)
#		$(SETMOD) abc $(abc_)
#		$(ADDMOD) abc -obj ... [if needed]
#		$(ADDMOD) abc -oper ... [if appropriate]
#		$(ADDMOD) abc -ps ... [if appropriate]
#
# If the abc feature requires the presence of some other features jkl and
# pqr, then the rules must look like this:
#
#	abc_=abc1.$(OBJ) ...
#	abc.dev: $(GS_MAK) $(ECHOGS_XE) $(abc_) jkl.dev pqr.dev
#		$(SETMOD) abc $(abc_)
#		...
#		$(ADDMOD) abc -include jkl pqr

# --------------------- Configuration-dependent files --------------------- #

# gconfig.h shouldn't have to depend on DEVS_ALL, but that would
# involve rewriting gsconfig to only save the device name, not the
# contents of the <device>.dev files.
# FEATURE_DEVS must precede DEVICE_DEVS so that devices can override
# features in obscure cases.
