# Slackware build script for canto-next

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

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

# This replaces the old abandoned canto SlackBuild, which was for canto 0.7.x.

# Note that the plugins are installed to /usr/lib/canto, even on
# 64-bit. This isn't a problem: they're Python scripts (not shared
# libs), and they don't even get used from their default location.
# You have to copy them to ~/.config/canto/plugins to use them.
# I considered changing this to /usr/share/canto, but I decided to
# leave upstream's default as-is.

# -L/usr/lib that causes the build to fail if 32-bit libncursesw
# and/or libreadline are installed.  Using the new setuptools on SBo
# works, but I don't want to put it in REQUIRES for everyone.
