Usage: ${_self} [-RsF] [-D num] [file/url]"
Flags:
-R # Remove the file after uploading.
-s # Make a screenshot and upload it instead of a file.
-F # Make a fullscreen shot instead of prompting for a window/area. Implies -s.
-D <num> # Delay the shot by <num> seconds.
-p # Make the file private. Requires \$secret to be set in the config.
Config options (~/.suprc):
secret # Your personal token. Get it at https://zfh.so/settings_form
cfg_screenshot_ext # Screenshot file type, used by scrot.
# Others are self-explanatory:
