- * mcvert.c - version 1.05 - 10 January, 1990
- * Written by Doug Moore - Rice University - dougm@rice.edu - April '87
-
- * Sun bug fixes, assorted stuff - Jim Sasaki, March '89
-
- * Changed default max_line_size from 2000 to unlimited - Doug Moore, April, '89
-
- * Sun 3/60 doesn't like odd-sized structs. Bug fixed - Doug Moore, April, '89
- * - aided by Spencer W. Thomas
-
- * Didn't handle properly many hqx files combined in one file. Bug fixed -
- * Doug Moore, June, '89
-
- * Modified to handle MacBinaryII specification. Jim Van Verth, Sept, '89
-
- * Fixed a bug when there are blank lines in hqx data, as happens when newline
- * get translated to CRLF and then to \n\n, common for some file transfers.
- * The last hqx line would be lost if the previous line was blank or junk.
- * Glenn Trewitt, Stanford University, 1990 (1.05)
-
- * Fixed a bug that occurred when extracting data or resource
- * forks on a Sun 4. It was a byte alignment problem.
- * Rick Zaccone, zaccone@bucknell.edu. April 1991. Version 1.6
-
- * Fixed:
- * Sent all "Converting ... " lines to stdout instead of stderr
- * Changed mactypes.h for HP-UX systems
- * Alan Danziger, aland@cs.brandeis.edu. October 1991. Version 1.6.5
-
- * ----------------------------------------------------------------------------
- * External
- * -----
- * Fixed buffering bug when converting very small MacBinary files to hqx files.
- * Provide helpful usage line.
- * Control "Converting ... " lines separately with -S flag.
- * Make encoding and decoding consistent by ignoring locked and init flags.
- * Clean up some error messages; check for more errors; provide errno on error.
- * Updated the man page.
- * -----
- * Internal
- * -----
- * Reformat source (sorry, local standard used by tools is tab space == 3)
- * Remove compiler warning messages.
- * Rename some variables.
- * Added some comments to code.
- * Added some offsets to struct definitions.
- * Since the makefile has compilation flags,
- * make the compiles depend on the Makefile.
- * -----
- * Thanks to all who have gone before for creating, maintaining,
- * improving, and providing this program and documentation.

- * Version 1.70 09Jul92
- * ----------------------------------------------------------------------------
-
- * ----------------------------------------------------------------------------
- * External
- * -----
- * Added -V (Verbose) option (includes debugging information).
- * Fixed bug converting hqx to MacBinary if last line is ":".
- * Avoided a silent error and quick exit situation.
- * -----
- * Internal
- * -----
- * Got rid of almost all lint (SunOS and HP-UX) error messages.
- * Compiled on SunOs, HP-UX, DomainOS.
- * Incorporated Parag Patel <parag@netcom.com> changes for AU/X.
- * Here's some diffs for really quick cheap hacks to get mcvert to compile
- * and run under A/UX. The main problem was that timeb does not exist, so
- * I added 2 #ifdef TIMEVAL to use the System-V timeval package instead.
- * The Makefile just has a -DTIMEVAL and a magic -U_SYSV_SOURCE to get
- * around a pre-defined type "ulong" in sys/types.h (thanks to Apple).
- * Did more code overhauling:
- * add lots more comments, rename variables, reformat source.
- * Put code in un_hqx to avoid suspected buffering problem.

- * Version 1.80 15Jul92
- * ----------------------------------------------------------------------------
-
- * ----------------------------------------------------------------------------
- * External
- * -----
- * Made hqx file scan processing much smarter
- * so, for example, info-mac/comm/qwk-reader.hqx,
- * complete with extraneous colons in column one, converts correctly
- * (problem described by Edward John Sabol <es2j+@andrew.cmu.edu>)
- * Avoid silly perror on usage message (prompted by Edward John Sabol)
- * Improve error message regarding improper format
- * Added more caveats to man page
- * -----
- * Internal
- * -----
- * Fixed typo's in printf lines to pass all expected arguments
- * (pointed out by Bo Holst-Christensen
- * [holst@diku.dk/dikubhc1@uts.uni-c.dk/holst@login.dkuug.dk])
- * Tweak Makefile to ease shar creation and special case ulong, not A/UX
- * Add yet more comments and debugging code

- * Version 1.82 30Jul92
- * ----------------------------------------------------------------------------
-
- * ----------------------------------------------------------------------------
- * External
- * -----
- * relax exactly 64 characters per incoming hqx file, and
- * handle files without trailing newline, so, eg,
- * Telnet2.5docs.sit.hqx now converts correctly
- * (failure reported by Justin Sullivan <justin@f2.facts.uky.edu>)
- * now also processes info-mac/app/road-map.hqx correctly
- * (failure reported by Victor Norton<norton@andy.bgsu.edu>)
- * rework the man page for improved clarity and completeness
- * -----
- * Internal
- * -----
- * avoid warning message from gcc on Sequent Balance mainframe
- * reported by Justin Sullivan <justin@f2.facts.uky.edu>
- * bump max incoming line length to 2048 from 255
- * add mcvert.ps target to Makefile

- * Version 1.83 03Aug92
- * ----------------------------------------------------------------------------
-
- * ----------------------------------------------------------------------------
- * External
- * -----
- * Found and fixed problem with byte ordering plaguing users of
- * Sequent's Balance running DYNIX, and DEC computers.
- * The error message looked something like
- * hqx_to_bin_fork: writing nnn too many bytes
- * Avoid generating debugging info if not to be printed -- cut runtime in half!
- * Generalize and incorporate -I (info) option processing provided by
- * Paul Franklin, Computer Enginnering, Univ. of Calif., Davis CA 95616
- * pdfranklin@ucdavis.edu.
- * Added heuristic to avoid false matches in mail headers.
- * problem expertly characterized, solution beta tested, and subsequent
- * improvement suggested by "Jim (J.) Lattanzi" <lattanzi@bnr.ca>
- * so segmented comp.binaries.mac files (either multi-file or concatenated
- * single file) should now convert correctly.
- * Added -H switch to disable heuristic.
- * Document heuristic in man page.
- * Fixed (long-standing) bug which precluded -p option from being recognized
- * and verified decompressing and unpacking of PIT files working.
- * Thanks to Dave Clemans for providing me with a version of PackIt.
- * Add the version to the extened Usage message emitted by the program.
- * Tune the syntax of the summary in the program and man page.
- * Cleaned up spelling mistakes in the man page.
- * -----
- * Internal
- * -----
- * Close all open streams --
- * fix for binfile by Paul Franklin <pdfranklin@ucdavis.edu>
- * Incorporate changes suggested by Barry_Wolman@transarc.com
- * to mactypes.h and Makefile for support of IBM RS/6000 running AIX 3.2
- * reformat Makefile to avoid long option lines
- * Identify the right Makefile lines for Irix too
- * suggested by Jack Repenning (jackr@dblues.wpd.sgi.com)
- * Clean up the stream handling and add mopen/mclose
- * avoid unnecessary /dev/null opens
- * all file open/close/read/write are checked for success
- * [still need to check putc/fputs/fprintf]
- * Lower lint content on SunOS and HP-UX.
- * avoiding all "sometimes ignored" lint messages.
- * Improve modularity with mopen/mclose/converting routines.
- * Tune debugging output information.
- * Verify that passes smoke tests on DomainOS/SunOS/HP-UX/ULTRIX.
- * Reformat these comments to avoid tabs.

- * be sold, by itself or as part of a collection of software. It may be freely
- * modified as long as no modified version is distributed. Modifications of

- *
- * ----------
- * Things that yet could be done:
- * ----------
- * provide compile time switch to avoid bzero and bcopy, and use memset
- * and memcpy instead (pointed out by linger@drystone.attmail.com)
- * provide header heuristic tuning option
- * to set length and/or same sensitivity.
- * check return values from putc/fputs/fprintf
- * From franklin@eecs.ucdavis.edu Thu Sep 24 16:39:21 1992
- * ...
- * In .bin->.hqx, check that the file is as long as you're expecting. This
- * could catch an error or a non-MacBinary file. I ran mcvert on a text
- * file accidentally, and got a segmentation fault. (It should at least
- * exit gracefully.) I'm guessing the error is from reading past the EOF,
- * but I'm not sure.
- *
- * Also, in .hqx->.bin, have -v print out input file names as well as output
- * file names. Once you're using more than one line, do it right. (Subject
- * to arbitrary interpretation, of course. ;-)) I noticed this because I
- * typed mcvert -I on a bunch of MacBinary files. mcvert just kept scanning
- * them, looking for a reasonable BinHex line and not finding one. Then, I
- * got a warning from the new heuristic mechanism. I had no idea which file
- * it came from.
