1.1.1.3 ! root        1: PGP Foreign Language Tools
        !             2: --------------------------
        !             3: 
        !             4: The "langtool" directory contains tools for manipulating foreign
        !             5: language translations for PGP's prompts and error messages.  The
        !             6: makefile is for Unix; the tools don't build cleanly under MS-DOS,
        !             7: although a little hacking should fix that.
        !             8: 
        !             9: One problem is that the code assumes getopt() is in the standard
        !            10: library, which it usually isn't with MS-DOS compilers, but you can
        !            11: steal getopt.c from the PGP source to fix that one.
        !            12: 
        !            13: In any case, the programs are:
        !            14: 
        !            15: pickpstr - this takes a list of filenames on the command line,
        !            16: searches them for LANG("...") constructs, and emits the "..." strings
        !            17: on standard output.  This is used to extract the strings to be
        !            18: translated from the PGP source.  The strings are found by searching
        !            19: for the 6-character LANG(" sequence.  Any spaces cause the string to
        !            20: be missed.  (the name comes from PSTR(), the macro that was replaced
        !            21: by LANG().)
        !            22: 
        !            23: killdups - this copies the outout of pickpstr from stdin to stdout,
        !            24: stripping out duplicates.
        !            25: 
        !            26: charconv - this converts between ISO Latin-1 and IBM PC code page 850
        !            27: character sets.
        !            28: 
        !            29: langtool - this is the big one, that merges various translation
        !            30: files, reporting which translations are missing, and so on.  It can
        !            31: extract a translation, merge translations, or check translation files
        !            32: for errors.
        !            33: 
        !            34: 
        !            35: The following notes were written by Branko Lankester for PGP 2.3a.
        !            36:

1.1.1.2   root       39:                     PGP language tools.
                     40: 
                     41: 
                     42: This is set of tools to maintain the PGP language files, with these
                     43: tools you can find new messages in the PGP source code and add them to
                     44: your language file.  You can also merge multiple languages into one file
                     45: and extract languages from a merged file.
                     46: 
                     47: 
                     48: Two programs are needed to extract the PSTR messages from the PGP source
                     49: code: "pickpstr" and "killdups", the batch file extract.bat will run
                     50: these programs on the PGP source files in the right order (the order is
                     51: important if you want to use diff to find differences).  You must run
                     52: extract.bat in the pgp src directory, this will create the file
                     53: "pstrmsgs".  I have included this file with these tools.
                     54: 
                     55: 
                     56: To create an up-to-date language file with one or more translations you
                     57: must use the "langtool" program with the merge (-m) option:
                     58: 
                     59: langtool -m -o newfile.txt pstrmsgs language.txt
                     60: 
                     61: language.txt is the old language file with your translations.  If there
                     62: is more than one language in this file you must specify the language
                     63: identifier after the filename.  The output file "newfile.txt" will
                     64: contain all messages from "pstrmsgs" and the translations from
                     65: "language.txt", new messages that are not present in language.txt will
                     66: have the line:
                     67: 
                     68: No translation
                     69: 
                     70: instead of the translated message, so you can use the "find" command of
                     71: your editor to find the untranslated messages by searching for this string.
                     72: 
                     73: 
                     74: If you want to combine several languages into one file you can also
                     75: use "langtool" with the -m option:
                     76: 
                     77: langtool -m -o language.txt lang1.txt lang2.txt
                     78: 
                     79: This will add the language in lang2.txt to the combined language file
                     80: "lang1.txt", the merged output will be in "language.txt".  If you 
                     81: want to add another language, run the same command again, but use the
                     82: output file from the last command (language.txt) as first inputfile:
                     83: 
                     84: langtool -m -o outfile.txt language.txt lang3.txt
                     85: 
                     86: "langtool -m" will use all translations from the first inputfile, and
                     87: one translation from the second input file.  If the second file contains
                     88: more than one language, you can specify the language you want after the
                     89: last filename.
                     90: 
                     91: 
                     92: You can also use langtool to extract one or more languages from a
                     93: combined language file:
                     94: 
                     95: langtool -x -o es-nl.txt language.txt es nl
                     96: 
                     97: will extract the languages with identifiers "es" and "nl" from
                     98: language.txt to the file "es-nl.txt"
                     99: 
                    100: 
                    101: If you want to run a simple check on a language file (the same check
                    102: that is done when pgp creates an index file), you can use the -c option:
                    103: 
                    104: langtool -c language.txt
                    105: 
                    106: This will print the number of messages, and the number of translations.
                    107: 
                    108: 
                    109: A language file for distribution should be in the PGP internal character
                    110: set: latin-1, for Russian it should be in KOI8.  This means that if your
                    111: system doesn't use a latin-1 or KOI8 character set you will have to
                    112: convert the language file to this internal format before you add it to
                    113: the distribution.  You can use the "charconv" program to do this:
                    114: 
                    115: charconv int language.in >language.txt
                    116: 
                    117: will convert from cp850 to the latin-1 internal format.  To convert from
                    118: internal to external, use "charconv ext file_name".  For conversion
                    119: between Russian character sets you need a different program.  Harry Bush
                    120: has sent me such a program, I assume the Russian translators already
                    121: have this program, but if someone needs it, I can send it to you.
                    122: 
                    123: 
                    124: Branko
