When you use the update command, Pyg searches through all installed packages and checks for updates. If there are some, Pyg installs them.
Before loading the entire list of installed packages, Pyg checks the ~/.pyg/installed_packages.txt file. If it exists Pyg will update only packages in that file:
$ pyg update
Cache file not found: $HOME/.pyg/installed_packages.txt

If you only need to download a package you can use the download command:
$ pyg download packname
If the requirement is not satisfied Pyg won’t download anything:
$ pyg download pyg==1024
E: Did not find files to download
After downloading a package, Pyg unpacks it:
$ pyg download -u pypol_
Found egg file for another Python version: 2.6. Continue searching...

Where to download the package, default to . (current working directory):
$ pyg download -d /downloads/python_downloads/ pyg
If the path does not exist, Pyg will create it.
The preferred file type for the download. Pyg looks for that file type and, if it does not exists, will try another extension:
$ pyg download -p .tar.gz pyg

If you need to execute many Pyg commands and you need root privileges (for example on Unix systems), you can fire up Pyg Shell and you are done:
$ pyg shell
Now you can use all Pyg’s commands plus 3 shell commands: cd, pwd, and ls:
pyg:/home/user$ check pyg
True
pyg:/home/user$ check pyg==0.3.2
True
pyg:/home/user$ ls
pkgtools pyg
pyg:/home/user$ pwd
/home/user
pyg:/home/user$ cd pyg
pyg:/home/user/pyg$ pwd
