The autodie pragma provides a convenient way to replace functions that normally
return false on failure with equivalents that throw an exception on failure.

The autodie pragma has lexical scope, meaning that functions and subroutines
altered with autodie will only change their behaviour until the end of the
enclosing block, file, or eval.

If system is specified as an argument to autodie, then it uses
IPC::System::Simple to do the heavy lifting. See the description of that module
for more information.
