# %%gobuild macro actually performs the command "go install", but the go
# toolchain will install to the $GOPATH which allows us then customise the final
# 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
#
#    example:  %gobuild foo ... bar
#    commands: go install importpath/foo...   (bar is ignored)
#
#    example:  %gobuild foo bar... baz
#    commands: go install importpath/foo
#              go install importpath/bar...
#              go install importpath/baz
