The "WIND" file holds the current region. Hopefully the documentation
will describe the concept, as it is central to many operations. It may
not mention the WIND file directly as that is part of GRASS'
internals, and shouldn't be relevant to the user.

Briefly: you can view the current region settings with "g.region -p",
and change them with other options to g.region, or with d.zoom. GRASS
commands which operate upon a specific region normally operate upon
the current region, rather than on the region covered by any
particular map; e.g. commands which operate upon raster maps usually
resample the maps according to the current region settings.
