CSTeX – Support for Czech/Slovak languages

This pack­age mir­rors the macros part of the home site's dis­tri­bu­tion of CSTeX. The li­cence (mod­i­fied GPL) ap­plies to some of the ad­di­tions that make it a Czech/Slo­vak lan­guage dis­tri­bu­tion, rather than the dis­tri­bu­tion of a ba­sic Plain/LaTeX dis­tri­bu­tion.
