+# %%gobuild macro actually performs the command "go install", but the go

+# install for the distro default locations.
+#
+# gobuild accepts zero or more arguments. Each argument corresponds to
+# a modifier of the importpath. If no arguments are passed, this is equivalent
+# to the following go install statement:
+#
+#     go install [importpath]
+#
+# Only the first or last arguement may be ONLY the wildcard argument "..."
+# if the wildcard argument is passed then the importpath expands to all packages
+# and binaries underneath it. If the argument contains only the wildcard no further
+# arguments are considered.
+#
+# If no wildcard argument is passed, go install will be invoked on each $arg
+# subdirectory under the importpath.
+#
+# Valid importpath modifier examples:
+#
+#    example:  %gobuild ...
+#    command:  go install importpath...
+#
+#    example:  %gobuild /...
+#    command:  go install importpath/...      (All subdirs NOT including importpath)
+#
+#    example:  %gobuild foo...
+#    command:  go install importpath/foo...   (All subdirs INCLUDING foo)
+#
+#    example:  %gobuild foo ...               (same as foo...)
+#    command:  go install importpath/foo...   (All subdirs INCLUDING foo)
+#
+#    example:  %gobuild foo/...
+#    commands: go install importpath/foo/...  (All subdirs NOT including foo)
+#
+#    example:  %gobuild foo bar
+#    commands: go install importpath/foo
+#              go install importpath/bar
