# This script will run a mass-check against all mbox files in a given
# set of directories.  The expected directory structure is:
#
# spamassassin				SA version to use
# corpus				location of all corpus files
#  run-masses				this script
#  spam					directory of spam
#  ham					directory of ham
#
# By default, the script looks for "spamassassin-head" which on my
# machine is the latest version from CVS.  You can easily change this
# by passing parameters to this script as such:
#
# run-masses ../spamassassin-garun --progress
#
# The first parameter is the directory to use for mass-check, and all
# other parameters are passed to mass-check itself.
#
# At the end, you will have a ham.log, spam.log, and results.log in the
# corpus directory.
#
# BTW: cpucount is a small script to figure out the number
# of CPUs on the current machine.  It is available from
# http://www.kluge.net/~felicity/random/
#

# Setup the path as necessary
PATH=/bin:/usr/bin:/usr/local/bin:${HOME}/bin:.

export PATH

# Use the specified directory for tests
if [ -z "$1" ]; then

else
	DIR="$1"
	shift
fi

# How many processes should we run at once?
PROCS=`cpucount`

# Where are our files located?

# do the mass-check
# class:format:path
