+The environments_scripts directory contains more directories, which map to environment types, each holding scripts and files useful to that environment. Each environment type also contains a "users" folder, which contains subfolders for each user on the system.  
+The build-crontab script uses the contents of these subfolders to create and install a customised crontab for each user in the folder. It does this by concatenating one liner crontabs into an uber crontab.
