# Reads a pcb2gcode drill file and creates individual files for each
# drill bit size. It will duplicate the preamble/postable between files.
# This is for programs like Universal Gcode Sender / UGS that do not let you
# change bits while streaming is paused because they do not allow you to move
# the head or reset the Z-axis while file streaming is paused.

-- Delete all from sender - https://gist.github.com/xunker/44fa4404c882c27e0ad25857e9470552
-- For the Mail.app in Mac OS X. It will search for all messages set by the sender of the email message currently open,
-- highlight them all and ask if you want to delete them. If you choose "yes" it will delete them for you and then clear
-- the search.
--
-- Important notes:
-- You can load this in Script Editor and then save it as an application so you can run it without Script Editor being open.
-- This does not work when Mail.app is in fullscreen mode; it must be in windowed mode.
-- You will need to enable "Assistive Devices" support for Script Editor (if run there) or for the .app you saved if you converted it to a standalone app.
