This module provides a Perl API for getenv(3), setenv(3) and unsetenv(3). It also can return all the environ variables.

Sometimes Perl invokes modules with underlaying C APIs which rely on certain environment variables to be set, if these variables are set in Perl and the glue code doesnt worry to set them on the C level, these variables might not be seen by the C level. This module shows what really the C level sees.
