Makefile copied from pokemath project Reads two files from sysfs: charge_now and charge_full under BAT0, then divides them using float math. Output is guaranteed to be stable across major versions. Supported options: -v gives verbose output for debugging purposes -h shows help text and exits -t gives terse output Known issues: The path to charge_now and charge_full is hard-coded. This utility will not work with batteries that do not happen to be named BAT0. The float value given by this program is not actually a percentage. TODO: Move help text #defines into a header file Add support to traverse /sys/class/power_supply and locate batteries Possibly add support to store default battery paths in /etc/battery_percent.conf DISCLAIMER: This program is already too overcomplicated and shows no signs of slowing down.

# Honestly still not sure what this directive does.
|
|
# It's an include directive, which processes all .d files that correspond to members of $(OBJ),
|
|
# with the hyphen in front meaning that it suppresses/ignores errors (from nonexistent .d files)
|
|
# Seems to be included under the stipulation that GNU make will auto-generate .d files based on
|
|
# a given file's #include directives?
