#
# Run JVCL on a spec
#
# Usage:
#
#    jvcl [-f spec-file] [-t temp-dir]
#
# If the `-f` option is omitted and no spec-file is provided, then jvcl will try to read
# a spec from stdin.
#
# Every run of JVCL will create a temp directory. You can either specify the name of the directory
# with `-t` (it will be created if it does not exist), or let jvcl create a temp directory for you.
#
# Note: this command will build the jvcl jar file if needed. The first time you run it, it might
# take a long time to start up.
