  I can't do anything about the install of these programs, but
once they are installed, they are now available to you just like
"dir", "more" and "xcopy". No extra DOS windows or anything.
You can call them from your program via a SYSTEM command, then
just read in the result file. Wicked fast and simple.

ie:
    iname = "abc123.JPG"
    listname = "invy.txt"
    system "grep" < iname < listname < "> result.txt"
    'read the contents of result.txt and do whatever you need to....

Note - my syntax may not be 100% correct, but you get the idea.

   Maybe you can take a look at how the install works and roll it
into your programs install. It is open source and you should be
able to modify things to bypass a separate install if that
really bothers you.
