This is a CD utility that I wrote that behaves like the UNIX (tm) cd
command.  It robustly allows wildcards, environmental variables, and
will use an environmental variable CDPATH to help locate regularly
accessed directories.  Unix folks may already appreciate the value of a
CDPATH.  The documentation is thorough.

This is the best free directory-changing program I've seen so far under
MS-DOS.  In less than 3000 bytes it gives you just about everything you
need in a directory changing program.  (Microsoft showed foresight when
it decided to make the current directory an attribute of the MS-DOS
kernel rather than an attribute of each process.  What the MS-DOS CD
command lacks, which is a lot, can therefore be fixed by nifty programs
like this one.)

MYCD allows the use of environment variables (prefixed by % or $) and
wildcards (* and ?) in a directory change string, so you can say

    cd $home/do*

and land in /binaries/ibm/pc/doc, provided you have an environment
variable

    HOME=\binaries/ibm/pc

already defined.

If an environment variable CDPATH is defined, it specifies a list of
directories to look inside for directories to change to.  So if CDPATH
contains a directory called \xyz, and you type "mycd xyuuu", and if
there is a directory xyuuu inside xyz, you will be changed to
\xyz\xyuuu, if it isn't found elsewhere.

Not bug-free, alas.  A leading forward slash in an environment
variable causes trouble.  So in the example given before, you could
not have an environment variable

    HOME=/binaries/ibm/pc

and make it work.
