configure.ac: changed AC_PROG_LEX to AM_PROG_LEX, as recommended by the automake manual (section 8.8, Yacc and Lex support)

  this uses the "missing" script if lex is not found.

added the pre-generated tex2xindy.c to the distribution.

+=head1 NAME
+
+tex2xindy - a preprocessor of the xindy index processor
+
+=head1 SYNOPSIS
+
+ tex2xindy [-o] [attr_file]
+
+=head1 DESCRIPTION
+
+B<tex2xindy> transforms a LaTeX index file C<.idx> (or an C<.aux>
+file) into a B<xindy> raw index file.
+
+It is a filter that reads from F<stdin> a file in the input format of
+LaTeX's raw index file, i.e., with C<\indexentry> tags. It outputs on
+F<stdout> a B<xindy> raw index file, i.e., with C<indexentry> clauses.
+
+If the option B<-o> is not specified, B<tex2xindy> handles ^^-notation
+of TeX and outputs the octet that is represented: C<^^ab> in the input
+gets output as the octet 0xab. If C<^^^^abcd> or C<^^^^^^^^abcdefab>
+are detected, they are output as is.
+
+If the option B<-o> is specified, B<tex2xindy> operates in I<Omega
+mode> and handles its ^^-notation: Then C<^^ab>, C<^^^^abcd>, and
+C<^^^^^^^^abcdefab> represent Unicode characters with code points
+0xab, 0xabcd, and 0xabcdefab respectively. They are output in UTF-8
+encoding.
+
+If the optional argument F<attr_file> is specified, B<tex2xindy>
+writes all index key attributes into this file.
+
+
+=head1 DEFICITS
+
+This program was written since it was not easily possible to extract
+the parser from the old makeindex system. Therefore it does not find
+all errors in the input as the makeindex(1) version.
+
+Additionally it uses only the default input specifiers of
+makeindex(1). If other input specifiers (cf. manual page of
+makeindex(1)) are needed, the input specifiers (starting from the
+pattern C<KEYWORD>, see below) must be changed and the program must be
+recompiled.
+
+The particular missing feature is configuration of the quote and the
+actual characters, maybe also the escape, subitem (level), and encap
+characters. Argument and range delimiters seem to be less of a problem.
+
+In fact, input markup handling (and thus B<tex2xindy>) should be
+incorporated into the B<xindy> kernel, to be able to specify
+configuration in xindy style files.

+  Revision 1.21  2006/07/30 09:44:04  jschrod
+      While quote is not output, escape+quote *is* output.
+
+  Revision 1.20  2006/07/18 21:40:45  jschrod
+      Add parenthesis as recommended by gcc -Wall.
+      Use ECHO instead of QUOTE_ECHO where quoting will not be needed.
+      Code cleanup: sanitize braces and indentation.
+
+  Revision 1.19  2006/07/18 21:26:34  jschrod
+      Add man page as POD to tex2xindy source.
+      Add support for ^^-notation, both in TeX and in new Omega mode.
+      Add usage message and proper option parsing.
+
+  Revision 1.18  2006/02/21 12:12:05  jschrod
+      Don't output escape or quote characters.
+
+  Revision 1.17  2006/02/21 02:05:00  jschrod
+      Quote really quotes the next char, now.
+
+  Revision 1.16  2005/06/27 20:49:06  jschrod
+      Keywords may be inmidst a line, as Jörg Sommer showed.
+      "." rule merging did not work for attributes, and for skiplocation.
+      Output error message if we come across chars outside our FSA.
+
+  Revision 1.15  2005/06/14 16:22:08  jschrod
+      Fold in changes from Thomas Henlich, as of 2000-02-14:
+  Paranoia fix: recognize KEYWORD only in INITIAL start condition.
+  Recognize \n and count lines (multiline entries do exist!).
+  Merged "." rules.
+  Fixed error messages (multiple ...).
+
+  Revision 1.14  2004/10/05 21:10:48  jschrod
+      Handles quote character correctly (bug ticket 1006128).
+  Test case: german-sty.
+
+  Revision 1.13  2002/01/29 13:32:58  thenlich
+  Fixed bug in crossref-to-subitem bugfix. The original one proposed by Roger Kehr
+  was right, only I copied it wrongly (shame on me). Thanks to Torsten Bronger
+  for pointing it out to me.
+
+  Revision 1.12  1999/10/13 08:06:44  kehr
+  Changed revision number message back to RCS-tag. No functional changes.
+
+  Revision 1.11  1999/10/13 08:05:10  kehr
+  Merged bugfix from Thomas Henlich with my own modifications.
+
+   1.8 Fixed minor quoting bugs (for increased makeindex compatibility).
+        1999-07-28 Thomas Henlich <henlich@mmers1.mw.tu-dresden.de>
+       Fixed crossref to subitem.
+        1999-09-23 Thomas Henlich <henlich@mmers1.mw.tu-dresden.de>
+
+   1.7 Fixed a bug concerning writing to and closing non-existing file (stat)
+       Fixed a bug concerning quoting the " character.
+       Enhancement for processing glossary files.
+        1999-06-14 Thomas Henlich <henlich@mmers1.mw.tu-dresden.de>
+
+  Revision 1.10  1999/09/23 06:53:32  kehr
+  Fixed wrong raw index generation for cross-ref keywords.
+
+  Revision 1.9  1999/04/27 09:01:17  kehr
+  Defined a clean exit code as suggested by Klaus Guntermann
+  <guntermann@iti.informatik.tu-darmstadt.de>.
+
+  Revision 1.8  1999/04/27 08:57:48  kehr
+  Added quoting patch sent by Thomas Henlich <thenlich@Rcs1.urz.tu-dresden.de>
+
+  Revision 1.7  1999/04/27 08:56:59  kehr
+  Another checkin.
+
+  Revision 1.6  1997/02/13 14:42:50  kehr
+  Minor changes.
+
+  Revision 1.5  1997/01/21 16:44:36  kehr
+  Bugfix: State <print> was not changed back to <key> if {LEVEL} was found.
+
+  Revision 1.4  1997/01/17 16:30:37  kehr
+  Rewrote makeindex4 and heavily modified tex2xindy.
+
+  Revision 1.3  1996/07/19  17:15:18  kehr
+  Made this program comaptible with lex by correctly enclosing all
+  actions--stupid bug, 'cause lex didn't complain and flex did some
+  wonderful matching of all the actions such that no error was
+  discovered.
+
+  Revision 1.2  1996/07/11  14:16:55  kehr
+  Complete Major checkin before changing the letter-groups.
+
+  Revision 1.1  1996/06/24  08:53:57  kehr
+  Initial checkin of the Makefile, README and tex2xindy.
