.SH DESCRIPTION
\fIr.latlong\fR creates a latitude (degree decimal) map, or longitude
if the \-l flag is used, from any map in any projection using PROJ.4 library.
This is an input to \fIr.sun\fR and \fIi.evapo.potrad\fR.
.SH NOTES
The PROJ.4 website.
.SH TODO
Datum transform is not implemented, the same datum is taken as output.
