In version 0.7.6, the collection of historic Greek ligatures and stylistic
alternates is complete. See the specimen file homer_sample.pdf for a
specimen; use hlig and salt to access the ligatures and alternates. Note
that it may be necessary to set the script to Greek explicitly to access
these features.
Note to persons compiling from source: Xgridfit is no longer used, but only
ttfautohint. Xgridfit may reappear later (if needed) for the purpose of
cleaning up ttfautohint's outlines. If you don't have ttfautohint installed,
you'll get the fonts without hints.
