# Computes forge-related variables for use in the rest of the spec file
# Control variables, flags and arguments:
#   %{forgeurl<number>}  the project url on the target forge
#   %{tag<number>}       the packaged tag, OR
#   %{commit<number>}    the packaged commit, OR
#   %{version<number>}   the packaged version
#                          – %{version}/%{version0} are set via:
#                              Version:
#                          – because git is lacking a built-in version
#                            reference, %{version<number>} will be translated
#                            into %{tag<number>} using unreliable heuristics;
#                            set %{tag<number>} directly if those fail
#   %{date<number>}      the packaged timestamp
#   …                    %forgemeta will compute a huge number of variables:
#                          — the packager can override it by setting some of
#                            those before the %forgemeta call
#                          – use the -i flag to list those variables
#   -z <number>          only process the zth block of definitions
#                        "" for the no-suffix block
#   -i                   list the resulting variable values
#   -s                   silently ignore problems in %{forgeurl<number>}
#   -v                   be verbose
#   -a                   process all sources in one go, instead of using
#                        separate -z calls
