/*
 *  afposncs.c - Appletalk Filing Protocol OS Normalizing for Character Sets
 *
 *
 *  afposncs contains the logic to normalize between an OS character
 *  set and a Macintosh character set.  It decides when a translation
 *  is necessary (based on file extentions and file types) and does
 *  the actual translation.  It is particularly useful for normalizing
 *  between unix files on machines that support an international
 *  character set and the macintosh character set.
 *  Note: logic to map between EOL chars was moved here as well.
 *
 *
 *  The intent is to provide some "transparency".  Translation is done
 *  based on a the ncs_transtable which defines which file
 *  type/creators get translated.  In addition, it possible to specify
 *  that files with particular suffixes (and file type/creators) get
 *  translated.
 *
 *  Caveat: much more massive changes must be made to allow for mapping
 *  from a single character to multiple (or vice versa).
 *
 *  Jan 1988 Dan Sahlin    Transliteration tables for .ascii, .swe,
 *                               .fin and .latin1
 *  Feb 1988 Charlie C. Kim  Rewrite all but tables.
