                           MODULES

RunAWK provides lots of AWK modules ready for use. All of them are
under modules/ subdirectory. They are installed by default.

    abort.awk,  alt_assert.awk
                     - power abort() and assert()
    alt_join.awk     - join :-)
    braceexpand.awk  - awk equivalent to shell's braceexpand functionality
    basename.awk, dirname.awk
                     - equivalents to basename(1) and dirname(1)
    embed_str.awk    - reads strings from AWK code
    exitnow.awk      -
    has_prefix.awk, has_suffix.awk
                     - trivial string functions
    match_br.awk     - find pair closed brackets in a string
    max.awk, min.awk, isnum.awk, abs.awk
                     - trivial math functions
    modinfo.awk      - routines to get an information about modules that
                       are in use
    multisub.awk     - another replacement functions
    pow.awk          - synonym for ^
    init_getopt.awk, alt_getopt.awk, power_getopt.awk
                     - POSIX/SUS compatible routines
                       for handling options EASILY ;-)
    readfile.awk     - read an entire file into variable
    runcmd.awk       - safe wrapper over system()
    shquote.awk      - escapes shell's special characters
    heapsort.awk, quicksort.awk, sort.awk
                     - sorting functions
    str2regexp.awk   - string to regexp routines
    tokenre.awk      - alternative mechanism for separating input into tokens
    xclose.awk, xgetline.awk, xsystem.awk
                     - functions to write robust programs
    tmpfile.awk      - generates names of automatically deleted tempfiles
    fieldwidths.awk  - portable equivalent of GNU awk's FIELDWIDTHS ;-)
    CR_in.awk        - removes CR symbols from input lines.
    trim.awk         - functions for trimming spaces from the string.
    trim_in.awk      - trims spaces from input lines.
    backslash_in.awk - treats backslash symbol at the end of line as
                       "this line will continue on the next one".
    ini.awk          - functions for reading Win .ini files.
    ftrans_in.awk    - handle data file transitions
    ord.awk          - character to id and id to character convertors

                           SCRIPTS

RunAWK also provides a few scripts:

   alt_getopt     - program arguments parser aware of long options,
                    alternative to POSIX getopts and getopt(1).
                    In addition to alt_getopt(1) utility alt_getopt.sh
                    shell library is also provided that provides
                    an alternative way for handling options.
   alt_getopt.sh  - shell library functionally equivalent
                    to alt_getopt(1)
