'''asna.py -- yoga/excercise timer

A simple routine timer for yogis and such people that use a
series of timers. The layout works in both portrait and landscape
modes. I've tested the code on iPad and iPhone 8 Plus. The
layouts work for me on those devices, your milage may vary. ;)

The default included pose list is what i normally do. You can
also feed the list in on the command line (such as might happen
if you feed the contents of a text block or file from the iOS
Shortcuts app).

The format is:
  <item>,<duration in seconds>

The duration can be a float or int value.
Blank lines are ignored. Lines not in the correct format will
crash the script. No error correction was attempted.

There shouldn't be any *reasonable* limit to the number of
poses, but I only tested up to about 30.

License:
  I release this into the public domain. Be excellent to
  each other.
