These functions allow access to get or change the values of environment
variables in a portable way. They are currently implemented under Win32 and
POSIX-like systems (Unix).

Remember that these functions add/change/delete environment variables of the
current process only. Child processes copy the environment variables of the parent
but do not share them (a wxSetEnv() in the parent process won't change the value
returned by wxGetEnv() in the child process and viceversa).

For more evoluted interprocess communication tecniques see @ref overview_ipc.
