+PGP Foreign Language Tools
+--------------------------
+
+The "langtool" directory contains tools for manipulating foreign
+language translations for PGP's prompts and error messages.  The
+makefile is for Unix; the tools don't build cleanly under MS-DOS,
+although a little hacking should fix that.
+
+One problem is that the code assumes getopt() is in the standard
+library, which it usually isn't with MS-DOS compilers, but you can
+steal getopt.c from the PGP source to fix that one.
+
+In any case, the programs are:
+
+pickpstr - this takes a list of filenames on the command line,
+searches them for LANG("...") constructs, and emits the "..." strings
+on standard output.  This is used to extract the strings to be
+translated from the PGP source.  The strings are found by searching
+for the 6-character LANG(" sequence.  Any spaces cause the string to
+be missed.  (the name comes from PSTR(), the macro that was replaced
+by LANG().)
+
+killdups - this copies the outout of pickpstr from stdin to stdout,
+stripping out duplicates.
+
+charconv - this converts between ISO Latin-1 and IBM PC code page 850
+character sets.
+
+langtool - this is the big one, that merges various translation
+files, reporting which translations are missing, and so on.  It can
+extract a translation, merge translations, or check translation files
+for errors.
+
+
+The following notes were written by Branko Lankester for PGP 2.3a.
