 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

+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).
