dwm_status.elv is the bootstrap script and is responsible for loading all modules within the lib/ directory. The user should edit this file and include / exclude any modules they wish to be displayed.
This script requires some binaries to be installed on the base system
dwm elvish df acpi ip date sensors free
The script can be executed via
elvish [..path..to..]/dwm_status.elv &
However to ensure you do not have to manually run the script each time dwm is launched it is recommended that the above command is added to the .xinitrc file, and will therefore be spawned on startx.
Thanks to @xiaq for feedback on the module loader / network module.
