Latin Modern family of fonts, based on the Computer Modern fonts released into public domain by AMS (copyright (C) 1997 AMS). The lm font set contains a lot of additional characters, mainly accented ones, but not exclusively. There is one set of fonts, available both in Adobe Type 1 format (*.pfb) and in OpenType format (*.otf). There are five sets of TeX Font Metric files, corresponding to: Cork encoding (cork-*.tfm); QX encoding (qx-*.tfm); TeX'n'ANSI aka LY1 encoding (texnansi-*.tfm); T5 (Vietnamese) encoding (t5-*.tfm); and Text Companion for EC fonts aka TS1 (ts1-*.tfm).

It is presumed that a potential user knows what to do with all these files. The author is Bogusław Jackowski.
