# Slackware build script for yt-dlp

# Written by B. Watson (urchlay@slackware.uk)

# Licensed under the WTFPL. See http://www.wtfpl.net/txt/copying/ for details.

# Note: I honestly prefer the standalone executable version of this,
# which I keep in ~/bin. It allows me to run "yt-dlp -U" as my user to
# get the latest version. However, since it's listed as a dependency
# for clipgrab, haruna, xdman, ytfzf, and an optional dependency for
# pipe-viewer, it has to exist on SBo.

# 20230711 bkw: updated for v2023.07.06
# 20230623 bkw: updated for v2023.06.22, added version check
# 20230402 bkw: updated for v2023.03.04
# 20230222 bkw: updated for v2023.02.17
# 20230104 bkw: updated for v2023.01.02
