+@url{http://proj4.org/, PROJ.4} project to the Go language.
+
+This package provides the following subpackages:
+@itemize
+@item @code{proj} (top-level): the Conversion API
+@item @code{proj/cmd/proj}: the simple proj command-line tool
+@item @code{proj/core}: the Core API, representing coordinate systems and
+conversion operations
+@item @code{proj/gie}: a naive implementation of the PROJ.4 gie tool, plus the
+full set of PROJ.4 test case files
+@item @code{proj/merror}: a little error package
+@item @code{proj/mlog}: a little logging package
+@item @code{proj/operations}: the actual coordinate operations; these routines
+tend to be closest to the original C code
+@item @code{proj/support}: misc structs and functions in support of the core
+package
