I believe all that remains now is to implement language variants (which should just be a matter of storing the strings from the command line and then comparing them with property values) and then figuring out how to verify that this is, in fact, equivalent to lt-comp.

Two issues:

• I'm inclined to not implement ACX support directly in this, since that would involve entirely duplicating the code in hfst-expand-equivalences
• I need to rename lt-proc's -v/--variant since it conflicts with the default -v/--verbose

ok, so if I run it on apertium-eng.eng.dix it runs out of memory and crashes, but if I run it on smaller things it does fine. Further investigation required.

Turns out the issue was forgetting to move on to the next character after reading a | in a regex.
