int system(string command);
  Execute command in a command shell.

  Returns:
  If command is null, returns nonzero if the command interpreter is found, and zero otherwise. If command is not null, returns -1 on error, or the exit status of command (which may in turn signal an error in command's execution).

  Note:
  On Unix systems, the homonym C function (which is accessible to D programs as std.c.system) returns a code in the same format as waitpid, meaning that C programs must use the WEXITSTATUS macro to extract the actual exit code from the system call. D's system automatically extracts the exit status.

int execv(in string pathname, in string[] argv);
int execve(in string pathname, in string[] argv, in string[] envp);
int execvp(in string pathname, in string[] argv);
int execvpe(in string pathname, in string[] argv, in string[] envp);
  Execute program specified by pathname, passing it the arguments (argv) and the environment (envp), returning the exit status. The 'p' versions of exec search the PATH environment variable setting for the program.

string getenv(in char[] name);
  Gets the value of environment variable name as a string. Calls std.c.stdlib.getenv internally.
