#
#		Standard variable names
#
#
# The fptools mk setup defines a set of standard names which are used
# by the standard targets provided by mk. One example of this is the
# use of standard names for specifying what files to compile, their
# intermediate/object code, and the name of the final
# executable. Based on the settings of these variables, the standard
# targets will generate/expand rules that automatically compile and
# link your program.
#
# The general rules:
#
#   SRCS - sources, might be prefixed to indicate what type of source
#          they are.
#   OBJS - object files (possibly prefixed).
#
#   PROG - name of final executable
#
# We attempt to automatically devine the list of sources $(SRCS) to
# compile by looking in the directories which may be specified by
# setting the $(ALL_DIRS) variable.  This is complicated by the fact
# that some files are derived from other files: eg. .hsc files give
# rise to -hsc.c and -hsc.h files, .ly files give rise to .hs files,
# and .hs files give rise to .hc files sometimes.

# So we figure out the sources in three stages: first figure out what
# sources we can find (this is $(ALL_SRCS)).  Then figure out all the
# "derived" sources (eg. A.hsc generates A.hs and A_hsc.c), and
# finally put all these together and remove duplicates (GNU make's
# handy sort function does the duplicate removing).

# HS_SRCS:   list of Haskell modules you want to compile.
#             (also use by depend rule).
# HS_OBJS:   list of corresponding object files
# HS_PROG:   program that is ultimately linked.
# HS_IFACES: list of interface files generated
#             (caveat: assuming no funny use of -hisuf and that
#               file name and module name match)
