+# @BLURB: An eclass for GoLang packages not installed inside GOPATH/GOBIN.
+# @DESCRIPTION:
+# This eclass allows to install arbitrary packages written in GoLang which
+# don't support being installed inside the Go environment.
+# This mostly includes traditional packages (C/C++/GUI) embedding tools written
+# in GoLang, and GoLang packages that need to be compiled with GCC instead of
+# the standard Go interpreter.
+#
+# @EXAMPLE:
+# Typical ebuild using golang-single.eclass:
+#
+# @CODE
+# EAPI=5
+#
+# GOLANG_PKG_IMPORTPATH="github.com/captObvious"
+# GOLANG_PKG_ARCHIVESUFFIX=".zip"
+# GOLANG_PKG_HAVE_TEST
+# inherit golang-single qt4-r2
+#
