#!/bin/sh
#
# A program to prepare batches of versions of the compiler.
#
# The control and output files are all in the subdirectory batch.
# The control files are $batch.MCFLAGS and possibly $batch.CFLAGS,
# $batch.GRADE, and/or $batch.MMAKE, where $batch is the last argument
# of makebatch. $batch.CFLAGS, $batch.GRADE and $batch.MMAKE are consulted
# if they exist.
#
# The control files $batch.MCFLAGS, $batch.CFLAGS and $batch.GRADE must have
# the same number of lines. Each line corresponds to a version of the compiler
# that is built with the MCFLAGS, EXTRA_CFLAGS and GRADE make variables
# being set from that line.
#
# The control file $batch.MMAKE contains an Mmakefile fragment that is
# included in the parameters of all the versions being built.
#
# The output goes in $batch.mercury_compile.$n.gz; the sizes of the versions
# are put in $batch.sizes. If a bootcheck fails, the bootcheck output goes
# in $batch.out.$n; the compiler will be thrown away unless the -f flag is
# given.
#
# The file $batch.checkpoint records which version is to be built next.
# Reinvoking makebatch while this file exists will cause it to start from
# that version. When makebatch exits normally, it removes the file to indicate
# completion.
