# Slackware build script for svox

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

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

# This is heavily based on Debian's packaging, see:
# https://packages.debian.org/source/sid/svox

# It's in the Debian non-free repo on a technicality: svox is free
# software released under the Apache-2.0 license, but the sources
# for the compiled voices (/usr/share/pico/lang/*.bin) are missing,
# so it doesn't quite comply with its own license.

# Notes to self:

# - The _8 in the version number is the Debian build number, keep it
#   in sync with future Debian updates.
# - "Upstream" here is Debian, not Android. Debian has svox's homepage
#   listed as "www.android.com", it seems more useful to set HOMEPAGE
#   to the Debian page for svox.

# 20210802 bkw: BUILD=2
# - update pico2audio script to support multiple words without quotes.
# - add man page for pico2audio.
# - update pico2wave man page.
# - add svox man page symlink, in case someone remembers the name of the
#   package but not the name of the binary.
