The L2 transducer is a transducer that models probable L2 errors.
Similar transducers are planned for Plains Cree and Northern Haida as well.

It is made as follows:

For __lexc__, the ordinary files are named as for all other languages, 
{{adjectives.lexc}}, etc. The L2 transducer files for adjectives, nouns and verbs in the stems and affixes folders are named {{affixes/adjectives-L2.lexc}}
etc. They shall be manually copied over from {{branches/errorfst}}.

For __twolc__, the ordinary file is called sme-phon-L1.twolc (and is
automatically copied over from the oldinfra file twol-sme.txt, by our
ordinary update script. The L2 file is called sme-phon-L2.twolc, and
is our source file for the L2 transducer.

__Note the not-so-elegant asymmetry__: sme-phon-L1.twolc is a file 
copied from oldinfra, and shall __not__ be edited. sme-phon-L2.twolc
is the source file itself, and __shall__ be edited. The derived
file sme-phon.twolc is the copy of either -L1 or -L2, and shall not be
edited.

To compile, in langs/sme:

{{{
./configure --enable-oahpa # to make the L2 transducer
./configure --disable-oahpa # to __not__ make the L2 transducer
make
}}}

The normal transducers have their normal names, the L2 transducers are called *-oahpa*.
