# Fedora macros, safe to use after the SRPM build stage

# Lists files matching inclusion globs, excluding files matching exclusion
# globs
#   – globs are space-separated lists of shell globs. Such lists require
#     %{quote:} use when passed as rpm arguments or flags.
# Control variables, flags and arguments:
#   %{listfiles_include}  inclusion globs
#   %{listfiles_exclude}  exclusion globs
#   -i <globs>            inclusion globs
#   -x <globs>            exclusion globs
#   …                     arguments passed to the macro without flags will be
#                         interpreted as inclusion globs

# Writes the contents of a list of rpm variables to a macro file
# Control variables, flags and arguments:
#   -f <filename>  the macro file to process:
#                    – it must contain corresponding anchors
#                    – for example %writevars -f myfile foo bar will replace:
#                        @@FOO@@ with the rpm evaluation of %{foo} and
#                        @@BAR@@ with the rpm evaluation of %{bar}
#                      in myfile
