Apps :: non-DSL application on a USB frugal install

hello,
I have a frugal DSL install on a USB stick, which works fine, and use several useful DSL extensions.
still, there a few apps which are not included in DSL base nor in DSL extensions which I would appreciate to have, so my question is:
is it possible to install a non-DSL application on a USB frugal install ? how ?
(I'm not sure it has its place here in the forum....)

You can install debian packages either with "sudo dpkg -i <filename>" (for local files) or "sudo apt-get install <packagename>" (from the internet). For apt-get you will need to first install apt-get ("enable apt" in the menu), and for some debian packages you will need to replace busybox with gnu-utils.
