# 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.
