I do not write programs just for Ubuntu. Seldomly I wrote Linux-only code.
Normally my programs are generic for all UNIX systems, even MacOS.

Therefore I do not support any "Ubuntu preferred" installation.
Anyone who thinks it is necessary is invited to add a specific installer.

Though I am German, I have NEVER written German programs. All my
programs are in English, because this is the world languange.
See http://fex.rus.uni-stuttgart.de:8080/
All other languages, even German, are contributions from others.
This is the way how open source works: someone creates an interesting
program and others contribute to it.

Back to fstools:
The traditional place to set $PATH is /etc/profile (or /etc/profile.d/*)
and $HOME/.profile

This is UNIX basic knowhow, which I premise, like how to start a shell in
a terminal or using a keyboard. I offer no extra explanation on these

It is called "/sw" - with a leading slash! It is important :-)

SWlink is just one script (not a binary executable) of the whole systems.
You cannot use it standalone.

I admit, the /sw documentation is not very good, because It was never
planned to use it outside of the University of Stuttgart.

I have added then http://fex.belwue.de/swinstall for "foreigners"
especially to have a generic update machanism for my fstools.

Not every UNIX has this file, not even every Linux!
It is just common for some distributions.
