This directory of files are copied into /home/opensim to act as the
startup and operation scripts for the instance of OpenSim that is running
in the docker container.

`bootOpenSim.sh` is run when the docker container starts and is responsible
for seeing that the configuration files and other setup (like DB) are initialized.
This script calls `firstTimeSetup.sh` for the first ever boot to do any
initial setup.
This script will fail if the environment variables `CONFIGKEY` or `EXTERNAL_HOSTNAME`
are not set.

`run.opensim.sh` starts the OpenSimulator instance.

`checkOpenSim.sh` is run periodically to make sure that the OpenSimulator instance
is running and, if not, save crash information (`captureCrash.sh`) and then
restart OpenSimulator.

`crontab` is set initially to run `checkOldLogFiles.sh` which rotates `OpenSim.log`.
