Package Manager Simulator

Write a simulator for a package manager.

The package dependencies is supplied in a file repo.db file such as:

a: b c d
d: e f
f: g

That is a requires b ,c, and d, while b, c, e and g does not depend on anything else. You can assume that there are no dependencies cycles in the repo.db

Your installed packages will be represented as a pkgs.db.

d
e
f

Write a pkg script such as.

pkg {install PKG|uninstall PKG|list}

Where:

• pkg install PKG will add PKG and all it dependencies (transitive included) into the pkgs.db
• pkg uninstall will remove PKG and all it packages that is dependent on it (transitive included) from pkgs.db
• pkg list will list the current packages in pkgs.db
