Not every time it starts up -- see below.

The .login is not sourced on every csh startup (e.g. when starting a new
xterm window), but only those for which the first char of argv[0] is a
hyphen (this denotes a login shell).  Csh can, however, be told to source
the .login file by having the first char be a hyphen.
