Hello,

I see that when you copy Cygwin executables (and dlls) to a random
windows machine and run (for example) bash.exe that Cygwin treats the
parent directory as the root, assigns it an 8-byte serial number and
records it in the user registry.  Can somebody point me to where the
code is that does this?  I presume somewhere under winsup/cygwin?

Also, are there pretty docs somewhere that detail the Cygwin internals,
architecture, etc?  It's making me curious...

Thanks!!
Daniel
