# Slackware build script for stretchplayer

# Upstream git is: https://gitlab.com/stretchplayer/stretchplayer.git
# Latest commits there are post 0.503 release, development
# stopped in 2014. Lots of nice new features there, including mp3
# support. Unfortunately building the latest git code results in a
# stretchplayer that segfaults on startup, and I don't have a fix, so
# I didn't try to package that. I did cherry-pick one commit though.

##### TODO:
# on every exit (close with the close button):
# corrupted double-linked list
# Aborted

# Patch by SlackBuild author. Allows tuning up and down by 10 cents
# (1/10 of a semitone) when holding the Shift key, or 1 cent when
# holding Control. Helps with stuff that was recorded slightly out of
# tune, or mastered from ancient tapes. Patch was sent upstream, but
# upstream isn't responding.

# Patch from upstream git, changes the stretch range from 25%-125%.
