There is a lot of "algorithms", about 50 kB of code:
- resuming upload and download after link failures
- sending multiple files as zip or tar containers
- deleting files
- configuring login
- handling HTTP proxy
- many other things...

No, I then have to maintain it. I do not like to support foreign code. I
was in this situation already. The client was written in Java, which I do
not know. I have had to throw it away some day, because I was not able to
fix the bugs.
Therefore I started to write the new client fexit in Python.
Here we are :-)

As I wrote: I have done this already with Perl/Tk and it was HASSLE.
No fun at all.

There is no directory view on server side.

I am not even a beginner GUI script writer and I do not want to become one.
GUIs are most superfluous and delay the work flow.

This is easy, because they have no alternative :-)

Yes. Horrible user interface and even more horrible to program :-}

There are no remote folders.

A VERY bad idea, if you have to send TB files.

It shall not look integrated. The user should think before using it.

There are no file manager which supports the F*EX protocol.
Therefore I am forced to write my own clients.
I am a lazy guy: if there is already a program, I will happily use it.
Only if there is none, I program it by myself.

There are no remote folders.
