+# Map Go information to rpm metadata. This macro will compute default spec
+# variable values.
+#
+# The following spec variable MUST be set before calling the macro:
+#
+#   goipath   the packaged Go project import path
+#
+# The following spec variables SHOULD be set before calling the macro:
+#
+#   forgeurl  the project url on the forge, strongly recommended, if it can not
+#             be deduced from goipath; alternatively, use -u <url>
+#   Version   if applicable, set it with Version: <version>
+#   tag       if applicable
+#   commit    if applicable
+#
+# The macro will attempt to compute and set the following variables if they are
+# not already set by the packager:
+#
+#   goname         an rpm-compatible package name derived from goipath
+#   gosource       an URL that can be used as SourceX: value
+#   gourl          an URL that can be used as URL: value
+#
+# It will delegate processing to the forgemeta macro for:
+#
+#   forgesource    an URL that can be used as SourceX: value
+#   forgesetupargs the correct arguments to pass to %setup for this source
+#                  used by %forgesetup and %forgeautosetup
+#   archivename    the source archive filename, without extentions
+#   archiveext     the source archive filename extensions, without leading dot
+#   archiveurl     the url that can be used to download the source archive,
+#                  without renaming
+#   scm            the scm type, when packaging code snapshots: commits or tags
+#
+# If the macro is unable to parse your forgeurl value set at least archivename
+# and archiveurl before calling it.
+#
+# Most of the computed variables are both overridable and optional. However,
+# the macro WILL REDEFINE %{dist} when packaging a snapshot (commit or tag).
+# The previous %{dist} value will be lost. Don’t call the macro if you don’t
+# wish %{dist} to be changed.
+#
+# Optional parameters:
+#   -u <url>  Ignore forgeurl even if it exists and use <url> instead. Note
+#             that the macro will still end up setting <url> as the forgeurl
+#             spec variable if it manages to parse it.
+#   -s  Silently ignore problems in forgeurl, use it if it can be parsed,
+#       ignore it otherwise.
+#   -p  Restore problem handling, override -s.
+#   -v  Be verbose and print every spec variable the macro sets.
+#   -i  Print some info about the state of spec variables the macro may use or
+#       set at the end of the processing.
