Then you can test to see if `%repo` is defined and if defined, use

distribution that does not provide it can rebuild the source RPM and
may not need to manually edit the spec file at all unless they need
conditionals other than the default.
The `%insinfo` macro
--------------------
Many GNU/Linux distributions have the `install-info` command installed
at either `/sbin/install-info` or at `/usr/sbin/install-info`. I
believe that is wrong because users may have a valid reason to need
the command outside the context of system documentation administration,
but it is what it is.
Unfortunately there does not seem to be a RPM standard macro that
defines the location of the `install-info` command, so to maintain at
least *partial* portability of spec files written for YJL, I created
the `%insinfo` macro that in YJL expands to `/usr/bin/install-info`
and when that macro is used, the spec file *must* have the following
fallback to define it if not defined:
%if %{!?insinfo:1}%{?insinfo:0}
%global insinfo /sbin/install-info
%endif
On YJL the macro is defined so the fall-back is not used, but where
the macro is *not* defined, the fallback then defines `%insinfo` to
`/sbin/install-info` which will at least be correct for *some* systems.
When a package installs `.info` files, the `%insinfo` macro *must* be
used in the `%post` scriptlet to add the info file to the info database
and `%insinfo --deleted` *must* be used in the `%preun` scriptlet to
remove the file from the info database *when the package is deleted
and not just being updated*.
The code block above *must* be used to define the `%insinfo` macro on
systems where it is not defined by default.
