+# This eclass provides a convenience src_unpack() which unpacks the
+# first tarball mentioned in SRC_URI to its appropriate location in
+# ${WORKDIR}/${P}, treating ${WORKDIR}/${P} as a go workspace.
+# Also, it provides a downstream method of vendoring packages.
+#
+# The location where the tarball is extracted is defined as
+# ${WORKDIR}/${P}/src/${EGO_PN}. The location of vendored packages is
+# defined as ${WORKDIR}/${P}/src/${EGO_PN%/*}/vendor to match Go's
+# vendoring setup.
+#
+# The typical use case is VCS snapshots coming from github, bitbucket
+# and similar services.
+#
+# Please note that this eclass currently handles only tarballs
+# (.tar.gz), but support for more formats may be added in the future.
+#
+# @EXAMPLE:
+#
+# @CODE
+# EGO_PN=github.com/user/package
+# EGO_VENDOR=(
+#	"github.com/xenolf/lego 6cac0ea7d8b28c889f709ec7fa92e92b82f490dd"

+#
+# SRC_URI="https://github.com/example/${PN}/tarball/v${PV} -> ${P}.tar.gz

+# @CODE
+#
+# The above example will extract the tarball to
