Configuring bash

[Elin Aronsen]

   Hi !

I certainly have a silly question since I am new at cygwin. I want to 
configure bash and I have to cd to the directory of the source code.
I suppose this is the code from the planetmirror local directory used as
local directory when using setup.exe to install cygwin. But if I use 
the bash shell and open it and do pwd, I get the answer /usr/bin 
indicating
that I am in an empty directory. I do cd .. and get to /usr and if I 
repeat, I get to / as an answer for pwd and now I cannot get higher up 
in
the tree. On using cygwin.bat in the folder cygwin, I cannot either cd 
to
the source code lying in the cygwin folder. Please help me.
Thanking you very much for all help.
