# When called with some number of arguments, this script:
#
# 1. Prints a special magic token on a line by itself.
# 2. Prints the number of args on a line by itself.
# 3. Prints each of the args in turn on their own lines.
# 4. Waits for input.
# 5. Reads a line (should be an integer), and exits with that status.

# Used by prcs.el as a value for $PRCS_DIFF_COMMAND or $PRCS_MERGE_COMMAND.
# The token is used to identify its execution in a general comint buffer.

# Do not let the uninterrupted token itself appear in any source code!
magic_1='MaGiC-PrCs-'
magic_2='CaLlBaCk-ToKeN'
# Read & write from/to tty because o.w. PRCS tries to snatch up our
# input and incorrectly buffer our output, devilishly.
