        * prims.c (prim_getenv): New primitive: getenv.

        * Makefile.am: Moved libcompat.a before libintl.a so intl library
        can use alloca.

        * De-ANSI-fied states sources since bison generated gram.c is
        already in K&R.

        * Makefile.am: Added many2html script.

        * enscript.st: Added support for multiple output languages and
        implemented HTML target for all supported input languages.

        * gram.y: changed top-level expressions to statements and moved
        subroutine definition from top-level to statements.  This allows
        conditional subroutine definitions.
        added tSYMBOL for state rule's expr part.  This allows
        user-definable matches.

        * enscript.st (tcl): Implemented Tcl highlighting.

        * defs.h (struct environment_st): Changed procedure call's
        environment from StringHash to linked list, this gives major
        speedup.

        * Version 0.9 of States, this is an early beta.
