View source for Install Apertium core using packaging

==== Cleaning up a mixed install ====
If you have installed some of the core tools from source and want to switch to packages, you can remove the source install with something like this. Be extremely careful with getting this right so it doesn't wipe your whole machine. (If Apertium isn't working no matter what you try, then this is a helpful step to take after uninstalling and reinstalling it)

<pre>
# Wipe most files
rm -rfv /usr/local/*/*apertium* /usr/local/*/*/*apertium*
rm -rfv /usr/local/bin/lt-* /usr/local/bin/lrx-* /usr/local/bin/lsx-*
rm -rfv /usr/local/*/*lttoolbox* /usr/local/*/*/*lttoolbox*
rm -rfv /usr/local/*/*hfst* /usr/local/*/*/*hfst*
rm -rfv /usr/local/bin/cg-*
rm -rfv /usr/local/*/*cg3* /usr/local/*/*/*cg3*

# Wipe any certain conflicting file
grep -h '^Package:' /var/lib/apt/lists/apertium.projectjj.com* \
| awk '{print $2}' | xargs -rn1 dpkg-query -L 2>/dev/null | grep '^/usr' \
| xargs -rn1 '-I{}' bash -c "if [[ -f '{}' ]]; then echo '{}'; fi;" \
| sed 's/\/usr\//\/usr\/local\//;' | xargs rm -fv
