# USAGE: random-commits.py
#
# Using the FILELIST (see config below), a series of COUNT commits will be
# constructed, each changing up to MAXFILES files per commit. The commands
# will be sent to stdout (formatted as a shell script).
#
# The FILELIST can be constructed using the find-textfiles script.
#

MAXFILES = 10	# up to 10 files at a time

for i in range(COUNT):
    n = random.randrange(1, MAXFILES+1)
    l = [ ]
    print "echo '--- begin commit #%d -----------------------------------'" % (i+1,)
