#
# A program to prepare batches of versions of the compiler.
#
# The control and output files are all in the dubdirectory batch.
# The control files are $batch.MCFLAGS and possibly $batch.CFLAGS
# and/or $batch.GRADE, where $batch is the last argument of makebatch.
# $batch.CFLAGS and $batch.GRADE are consulted if they exist.
#
# All the control files 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 output goes in $batch.mercury_compile.$n.gz; the size of the versions
# are put in $batch.sizes. If a bootcheck fails, the bootcheck output goes
# in $batch.out.$n.
#
# The file $batch.checkpoint records which version is to be built next.
# Reinvoking makebatch while this file exist will cause it to start from
# that version. When makebatch exits normally, it removes the file to indicate
# completion.
