:: Make --no-ri --no-rdoc default gem install options (without documentation)
:: Possible variations:
:: For every user:
::    echo gem: --no-ri --no-rdoc > "%PROGRAMDATA%\gemrc"
:: Only for you
::    echo gem: --no-ri --no-rdoc >> "%USERPROFILE%\.gemrc"
::
:: Note: In Windows, %PROGRAMDATA% is /etc on Linux
::
:: But finally, the best way to do it. See: http://stackoverflow.com/a/7662245/1579985

My explanation of the main concepts in Rust

There are three main concepts with Rust:

1. Ownership (only one variable "owns" the data at one time, and the owner is in charge of deallocating)
2. Borrowing (you can borrow a reference to an owned variable)
3. Lifetimes (all data keeps track of when it will be destroyed)

These are fairly simple concepts, but they are often counter-intuitive to concepts in other languages, so I wanted to give a shot at
