document openils-mapper code for enriched EDI

[Ben Shum]

Evergreen master

So, since bug 1030041 was merged back in 2.3 to bring us enriched EDI for acquisitions, there's been an undocumented need to use a custom branch of the ruby openils-mapper bits. Until such time as the mainline code is adapted with berick's custom changes, we need to include some additional steps in our acq edi setup documentation to note the need for the custom branch.

Link to the custom branch: https://github.com/berick/openils-mapper/tree/GIR-segments-for-copy-data

Documentation to follow.

For reference:

git clone https://github.com/berick/openils-mapper
cd openils-mapper/
git checkout -b GIR-segments-for-copy-data origin/GIR-segments-for-copy-data
sudo cp lib/openils/mapper.rb /usr/lib/ruby/gems/1.8/gems/openils-mapper-0.9.9/lib/openils/mapper.rb
sudo cp lib/edi/mapper.rb /usr/lib/ruby/gems/1.8/gems/openils-mapper-0.9.9/lib/edi/mapper.rb

Paths and version numbers may vary.

Just a note: when installing rubygems from the apt package, the gems will live in /var/lib... instead of /usr/lib...
