Glob Expansion
--------------

Searches for files that match the glob pattern specified, and inserts all
of them onto the command line. It will match glob patterns with '*' and
'~' characters. Glob pattern matching is not performed on the first
argument of a command.

Examples
--------
    ls *.c
- This will list every file whose name ends in ".c"

    cd ~/Documents
- This will change directory into the Documents folder of the 
  user's home directory

    cat file.txt > ~/out.txt
- This will write the contents of file.txt to out.txt in the user's
  home directory
