[Tinyos-help] Upgrading from TinyOS 1.x to TinyOS 2.x

[Max CORTIANA]

I've followed the article "Upgrading from TinyOS 1.x to TinyOS 2.x", 
located at page 
"http://www.tinyos.net/tinyos-2.x/doc/html/upgrade-tinyos.html" and now 
my old Tinyos-1.x and 2.0 share the same cygwin installation.

The problem I had was the creation of 2 scripts used to modify 
environment variables. If scripts are executed in a shell with the syntax
./script
then environment variables are not changed in the shell environment 
(scripts are executed in they environment which is the copy of the 
caller env).
The solution I've found is to call scripts in such way:
(dot)(space)(name of script)
i.e.:
. script

With this syntax Linux executes programs in the caller environment and 
every modification is persistent after programs end.

If you think this information is useful, I kindly ask to append it in 
the "Upgrading from TinyOS 1.x to TinyOS 2.x" article.
