## 8.33 Config

Used to access configuration information. When Perl is built, the Configure script obtains and saves this information in a hash, `%Config`, in Config.pm itself. Config checks to be sure it's running with the same Perl version as the one that created the hash.

The index into the hash is the shell variable name. `%Config` is always exported; the following three functions are exported on request:

- config_sh
- config_vars
- myconfig
