PORTING - read this only if the program won't compile.
Makefile - read this next, adapt it as needed (particularly
the location of the old existing file command and
the man page layouts), type "make" to compile,
"make try" to try it out against your old version.
Expect some diffs, particularly since your original

the current magic file, or may even not use the
magic file.

Fix output so that tests for MIME and APPLE flags are not needed all
over the place, and actual output is only done in one place. This
needs a design. Suggestion: push possible outputs on to a list, then
pick the last-pushed (most specific, one hopes) value at the end, or
use a default if the list is empty.
Continue to squash all magic bugs. See Debian BTS for a good source.
Store arbitrarily long strings, for example for %s patterns, so that

/*
* This table reflects a particular philosophy about what constitutes
* "text," and there is room for disagreement about it.
*
* Version 3.31 of the file command considered a file to be ASCII if
* each of its characters was approved by either the isascii() or
* isalpha() function. On most systems, this would mean that any
* file consisting only of characters in the range 0x00 ... 0x7F
* would be called ASCII text, but many systems might reasonably
* consider some characters outside this range to be alphabetic,
* so the file command would call such characters ASCII. It might
* have been more accurate to call this "considered textual on the
* local system" than "ASCII."
*
* It considered a file to be "International language text" if each
* of its characters was either an ASCII printing character (according
* to the real ASCII standard, not the above test), a character in
* the range 0x80 ... 0xFF, or one of the following control characters:
* backspace, tab, line feed, vertical tab, form feed, carriage return,
* escape. No attempt was made to determine the language in which files
* of this type were written.
*
*
* The table below considers a file to be ASCII if all of its characters
* are either ASCII printing characters (again, according to the X3.4
* standard, not isascii()) or any of the following controls: bell,
* backspace, tab, line feed, form feed, carriage return, esc, nextline.
*
* I include bell because some programs (particularly shell scripts)
* use it literally, even though it is rare in normal text. I exclude
* vertical tab because it never seems to be used in real text. I also
* include, with hesitation, the X3.64/ECMA-43 control nextline (0x85),
* because that's what the dd EBCDIC->ASCII table maps the EBCDIC newline
* character to. It might be more appropriate to include it in the 8859
* set instead of the ASCII set, but it's got to be included in *something*
* we recognize or EBCDIC files aren't going to be considered textual.
* Some old Unix source files use SO/SI (^N/^O) to shift between Greek
* and Latin characters, so these should possibly be allowed. But they
* make a real mess on VT100-style displays if they're not paired properly,
* so we are probably better off not calling them text.
*
* A file is considered to be ISO-8859 text if its characters are all
* either ASCII, according to the above definition, or printing characters
* from the ISO-8859 8-bit extension, characters 0xA0 ... 0xFF.
*
* Finally, a file is considered to be international text from some other
* character code if its characters are all either ISO-8859 (according to
* the above definition) or characters in the range 0x80 ... 0x9F, which
* ISO-8859 considers to be control characters but the IBM PC and Macintosh
* consider to be printing characters.

* This table reflects a particular philosophy about what constitutes
* "text," and there is room for disagreement about it.
*
* Version 3.31 of the file command considered a file to be ASCII if
* each of its characters was approved by either the isascii() or
* isalpha() function. On most systems, this would mean that any
* file consisting only of characters in the range 0x00 ... 0x7F
* would be called ASCII text, but many systems might reasonably
* consider some characters outside this range to be alphabetic,
* so the file command would call such characters ASCII. It might
* have been more accurate to call this "considered textual on the
* local system" than "ASCII."
*
* It considered a file to be "International language text" if each
* of its characters was either an ASCII printing character (according
* to the real ASCII standard, not the above test), a character in
* the range 0x80 ... 0xFF, or one of the following control characters:
* backspace, tab, line feed, vertical tab, form feed, carriage return,
* escape. No attempt was made to determine the language in which files
* of this type were written.
*
*
* The table below considers a file to be ASCII if all of its characters
* are either ASCII printing characters (again, according to the X3.4
* standard, not isascii()) or any of the following controls: bell,
* backspace, tab, line feed, form feed, carriage return, esc, nextline.
*
* I include bell because some programs (particularly shell scripts)
* use it literally, even though it is rare in normal text. I exclude
* vertical tab because it never seems to be used in real text. I also
* include, with hesitation, the X3.64/ECMA-43 control nextline (0x85),
* because that's what the dd EBCDIC->ASCII table maps the EBCDIC newline
* character to. It might be more appropriate to include it in the 8859
* set instead of the ASCII set, but it's got to be included in *something*
* we recognize or EBCDIC files aren't going to be considered textual.
* Some old Unix source files use SO/SI (^N/^O) to shift between Greek
* and Latin characters, so these should possibly be allowed. But they
* make a real mess on VT100-style displays if they're not paired properly,
* so we are probably better off not calling them text.
*
* A file is considered to be ISO-8859 text if its characters are all
* either ASCII, according to the above definition, or printing characters
* from the ISO-8859 8-bit extension, characters 0xA0 ... 0xFF.
*
* Finally, a file is considered to be international text from some other
* character code if its characters are all either ISO-8859 (according to
* the above definition) or characters in the range 0x80 ... 0x9F, which
* ISO-8859 considers to be control characters but the IBM PC and Macintosh
* consider to be printing characters.
