# https://fedoraproject.org/wiki/Packaging:Guidelines#Architecture_Build_Failures
#If a Fedora package does not successfully compile, build or work on an
#architecture, then those architectures should be listed in the spec in
#ExcludeArch. Each architecture listed in ExcludeArch needs to have a bug filed
#in bugzilla, describing the reason that the package does not compile/build/work
#on that architecture. The bug number should then be placed in a comment, next
#to the corresponding ExcludeArch line. New packages will not have bugzilla
#entries during the review process, so they should put this description in the
#comment until the package is approved, then file the bugzilla entry, and
#replace the long explanation with the bug number. The bug should be marked as
#blocking one (or more) of the following bugs to simplify tracking such issues:
