## snooze time = time between each play in seconds

## INVOCATIONS:
## wae c[at]			print this file on standard output
## wae h[elp]			show the help screen
## wae *.mp3 path/*.mp3 8 32	play sound files and wait from eight to thirty two seconds between each play
## wae file.mp3			play one sound file continually using default snooze time to pause between each play
## wae w				print this file on standard output including newline, word, and byte counts

## OPTIONS WHILE PLAYING:
## a[bort]		abort at end of current task
## b[reak]		break at end of current task
## c[at]		cat this file at end of current task
## CTRL+\		quit current task immediately 
## CTRL+C		quit wae session immediately 
## e[xit]		exit at end of current task
## h[elp]		print help at end of current task
## l[ist]		list playlist at end of current task
## q[uit]		quit at end of current task
## s[huffle]	shuffle playlist at end of current task
## w[c]		print file, and print newline, word, and byte counts for this file on standard output at end of current task

## SYNTAX:
## wae audio_file[s] [audio files] [min snooze time] [max snooze time]

## Variables STMN=32 and STMX=496 can be edited in order to set the default minimum and maximum snooze times.  Please see 'wae cat' for more information.

## Multiple sessions can be used in order to run commands 'wae arguments' simultaneously and to switch seamlessly between plays.

## The command 'wait an event' is derived from the theories of gray music cognition and music as medicine.  Termux group discussions circa 2018 at Termux community channels were very helpful before the SDRausty account was banned by Termux curators doing the work of open source code squatters.  Please reference https://github.com/SDRausty/builtAPKs/issues/2 for more information about the topic of open source code squatting.
