# Description:

# Function Like Makefile (FLM) to create a resource header (.rsg)

# and resource files (.rsc, .r01, .r02 etc.)

#

#

## Parameters that are expected:

# TARGET

# TARGETPATH

# LANGUAGES

# HEADER

# HEADERONLY

# EPOCROOT

# MMPDEFS

# PRODUCT_INCLUDE

# SYSTEMINCLUDE

# USERINCLUDE

# GNUCPP

# GNUSED

# RCOMP

# OUTPUTPATH

# SOURCE

# BINCOPYDIRS

# The rss is pre-processed once for each language and results

# in a file with extension r$(LANGUAGE) where $(LANGUAGE) is

# either "sc" or a 2 (or more) digit number.

# There is only one resource header (.rsg) file and we only

# make that if we are asked.
