No matter how smart and friendly this interface will be, it won't
support every possible way of using `grep'.  That's why sometimes you
will need to use `grep' in conjunction with `find'.  Using `find' for
recursively searching subdirectories is of course redundant in DJGPP,
since we have the "..." wildcard, courtesy of DJ.  But `find' can
choose files it passes to `grep' using much more powerful and
elaborate tests than you can ever do with `grep' alone.  For example,
you can limit the recursion to a certain depth of subdirectories,
search only files created within last 2 days, or which are newer than
a certain file, or larger than N bytes, etc.
