# -*- Makefile -*-

# Generic makefile for ods2
#
# This tries really hard to be OS-agnostic, because
# otherwise, every little change means updating all
# the os-specific makefiles.
#
# For Unix and Unix-ish OSs, variables are defaulted
# in makefile.unixdefs, which is included by
# makefile.<osname>.  Per-OS customizations are set
# by makefile.<osname>, which then includes this file.
#
# If your make doesn't support include (are any left?),
# combine the files with an editor.
#
# Life will be simpler if you softlink Makefile to makefile.<osname>
#  e.g. ln -s makefile.unix Makefile
#
# ###

# See makefile.unixdefs for a list of the available variables.

# VHD format options

# #####################################################

# Language files are of the form LL_CC.{msg, hlp}
# Where: LL is a language code (e.g. en), and
#        CC is a country code (e.g. us)
# .msg files are the message definitions
# .hlp file  are the helpfile text
#
# The base language is en_us, but translations are welcome.

# Filenames of these forms will automatically generate the
# runtime-loadable help (.hlb) and message (.mdf) files.

# Note that translated messages from a VMS system are required
# for each language; these are generated with the (DECUS)
# unmessage utility, are are named "vms_msgdump.<lang>.msg.
# Output from the message utility has more details.
