/***************************************************************************
* PAN1PTBL.C - ElseWare PANOSE(tm) Font Mapper penalty database.
*
* $keywords: pan1ptbl.c 1.9 15-Apr-94 3:53:54 PM$
*
* This is a stand-alone program that writes a 'C' style header file
* containing the penalty tables for the font mapper. The tables are
* in MEMORY format, e.g., they use Intel or Motorola byte ordering
* depending on the platform upon which the program is compiled.
*
* This program should accompany ELSEPAN.C, the ElseWare PANOSE Mapper
* source code, which assumes the output from this program is in a file
* named PAN1PTBL.H.
*
* The command-line is as follows:
*
* pan1ptbl [-b] [-v] [-l] [-d] <in-filename> <out-filename>
*
* where:
*
* -b means produce a binary file (instead of a 'C' struct)
* -v means get from and put to version control
* -l means precede the struct with the keyword FAR
* -d means dump the database to the screen
* <in-filename> is the name of the text file containing the
* penalty database (PAN1PTBL.TXT)
* <out-filename> is the name of the output file (PAN1PTBL.H)
*
* The '-b' switch causes the MEMORY representation of the struct to be
* dumped to file (in binary form). The normal behavior (no '-b' switch)
* is to produce a text file containing a C-style declaration of the
* struct.
*
* The '-v' switch presumes the user has Sorcerer's Apprentice, and causes
* a 'vout' of pan1ptbl.h followed by a 'vin' of the newly generated file.
* Notice that Sorcerer's Apprentice ignores the transaction if the file
* is not different from the previous revision.
*
* The '-l' switch causes the database to be declared 'FAR,' which in
* DOS and Windows large model programs causes the data structure to be
* placed in its own data segment.
*
* The '-d' switch causes a textual description of the database to be
* dumped to stdout for debugging purposes.

* 1.4 3-Feb-93 msd Added generic line-read routine that can handle both mac- and pc-format test files.
* 1.5 6-Feb-93 msd Init reserved bye in C0 penalty header.
* 1.6 18-Feb-93 msd Implemented binary file writing, init penalty table byte-ordering variable, and C4 ptbl compression( new version of ptbl ). Identical tables are not repeated.
* 1.7 26-Feb-93 msd Don't abort on weight values of zero( just warn ). Also repaired line counter.
