[Tutor] trouble installing library

[Lolo Lolo]

guys having got the install to work, a part of the process fails me.. the full code instruction is:
 
$ virtualenv --no-site-packages gmapenv 
$ cd gmapenv 
$ ls 
bin/  include/  lib/ 
$ . bin/activate
 
since im on windows i used dir instead of ls, but this line:
 
$ . bin/activate
 
is not recognised as a command. If i try to open it wth python cmd says no such file or directory
