| MODULE OVERVIEW |
+-----------------------------------------------------------------------------+
archiver:
- archives and compresses tablet data files
webserver:
- communicates with tablets. Indexes data from tablets, pushes updates
to tablets...etc
space_manager:
- determines if there is sufficient free space on the Pi and
if there is not, deletes files to make room
file_mover:
- Moves archived tablet data to inserted USB stick, then
backs up transfered files, and deletes the backed up archives
utils:
- contains utility functions used for logging, counting files,
manipulating arrays, and clearing directories used in testing.
build.sh:
- To be run inially to install the server on the pi and create all
necessary directories...etc
config.sh:
- single point of truth for directories used in multiple scripts
Note:
- setup files in each directory are to be run at build time for the
purpose of creating the directories/scheduling cron jobs neccessary
for the given module

| TECHNICAL NOTES |
+-----------------------------------------------------------------------------+
- Build script must be run from inside the build directory
- You can check if a build was successful by looking at the build log
- usb_id file in file_mover directory must be on usb inserted into
raspberry pi if you want files to be moved to that usb
- name of update script that will be run if on usb is in config
- Directories used by tests must be empty when tests are run
USB must be plugged into pi when running file_mover tests
- Run .sh scripts with ./ if in directory or path to script NOT with sh
- Use python3 to run python scripts. Everything should be backwards compatable,
but the scripts have only been tested using python3
- Syntax for passing array to function array[@]
Syntax for getting array param param=("${!1}") # replace 1 with param number
