# The folloing describes an example usage:
#
# This script may be used to build all of M4M including up-to-date
# Tables of Contents, Table of Figures, Table of Tables, Indices,
# and Bibliographies. Since this build takes roughly 2-3 hours
# (depending on the speed of the CPU), the Mac computer is
# `caffeinated' so that it doesn't go into Sleep Mode in the middle
# of a build.
#
# This bash script should be executed by the following commands (for example)
# to build all of M4M:
# . caffeinate_script.sh build_Scripts_M4M_all_copy_aux.sh
# or, for example, to build just a single Thinking Problem:
# . caffeinate_script.sh M4M-CM-Schulers-Pendulum-Thinking-Problem.sh
#
# If the script returns to Terminal input, and if %1 job is stopped, then
# enter "%1" to get the job running again and hit "RETURN" to restart
# the caffeinate script.
#
# You should probably set GPG_wait_for_input="YES" in your input script so that
# the build will wait for you to return to enter the GPG passphrase instead of
# just timing out. After stopping the first time, you can enter "NO" in order
# that the build-box.sh script does not stop for future GPG passphrases (I have
# set my GPG Suite remember passphrase time to 1200 or 3600 seconds instead of
# the default 600 seconds).
#
# When the script finishes (returns to Terminal prompt), the M4M build is complete.
