updated to 0.18.0

  Makefile:
    !!! "install-dirs" target has been renamed to \ 
"installdirs" !!!

    - At compile time MODULESDIR can contain a *list* of
      colon-separated directories,
      e.g. /usr/local/share/runawk:/usr/local/share/awk

  - power_getopt.awk, alt_getopt.awk and init_getopt.awk:
    - Support for multiply applied options, e.g. -vvv for increasing
      verbosity level. If option without arguments is multiply
      applied, getarg() function returns a number of times it was
      applied, not just 0 or 1.

  New modules:

    - init_getopt.awk using alt_getopt.awk and used by power_getopt.awk.
      Its goal is to initialize `long_opts' and `long_opts' variables
      but not run `getopt' function.

    - heapsort.awk  -  heapsort :-)
    - quicksort.awk - quicksort :-)
    - sort.awk      - either heapsort or quicksort,
                      the default is heapsort.
      Unfortunately GAWK's asort() and asorti() functions
      do *not* satisfy my needs. Another (and more important) reason
      is a portability.

  Improvements, clean-ups and fixes in regression tests.

  runawk-0-18-0 was successfully tested on the following platforms:
    NetBSD-5.0/x86, NetBSD-2.0/alpha, OpenBSD-4.5/x86,
    FreeBSD-7.1/x86, FreeBSD-7.1/spark, Linux/x86 and
    Darwin/ppc.
