Wgetrc Location
===============
When initializing, Wget will look for a "global" startup file,
`/etc/wgetrc' by default (or some prefix other than `/usr/local', if
Wget was not installed there) and read commands from there, if it
exists.
Then it will look for the user's file. If the environmental variable
`WGETRC' is set, Wget will try to load that file. Failing that, no
further attempts will be made.
If `WGETRC' is not set, Wget will try to load `$HOME/.wgetrc'.
The fact that user's settings are loaded after the system-wide ones
means that in case of collision user's wgetrc _overrides_ the
system-wide wgetrc (in `/etc/wgetrc' by default). Fascist admins, away!
