#    Wget 1.11 for VMS - MMS Dependency Description File.
#
#    MMS /EXTENDED_SYNTAX description file to generate a C source
#    dependencies file.  Unsightly errors result when /EXTENDED_SYNTAX
#    is not specified.  Typical usage (from the [...src] directory):
#
#    $ @ [-.VMS]VMS-WGET.COM DEPS [DASHD] [HPSSL|NOSSL] [NOSKIP] [CLEAN|PURGE]
#
# This description file uses this command procedure:
#
#    [-.VMS]COLLECT_DEPS.COM
#
# MMK users without MMS will be unable to generate the dependencies file
# using this description file, however there should be one supplied in
# the kit.  If this file has been deleted, users in this predicament
# will need to recover it from the original distribution kit.
#
# Note:  This dependency generation scheme assumes that the dependencies
# do not depend on host architecture type or other such variables. 
# Therefore, no "#include" directive in the C source itself should be
# conditional on such variables.
#
# Note:  For no apparent reason, Wget code uses "system include"
# brackets (<>) for "config.h", so /MMS_DEPENDENCIES =
# NOSYSTEM_INCLUDE_FILES is useless here.  Thus, we rely on
# COLLECT_DEPS.COM to filter out the system includes from the
# dependencies.
