# At some point I'll update this to match Slackware's paths, but
# if you want to install this where Slackware would, add (for 64-bit)
# something like so:
# --prefix=/usr --libdir=/usr/lib64

# Configure the build
test $(uname -m) = 'x86_64' && ./configure --libdir=/usr/local/lib64
test $(uname -m) != 'x86_64' && ./configure

# Build it
make

# Test the build
make check

# Requires Sphinx (as root: 'pip install -U Sphinx')
# View with 'lynx doc/_build/html/index.html' (or go to the docs URL above)
make html

su

# Remove the Slackware package, if there is one
