misc/retry/Makefile

11

Please also define LICENSE_FILE

13

There's a man page in the tarball already?

15

Is autoreconf really needed?

17

You probably want GNU_CONFIGURE here as it's not a custom configure script

Thanks @diizzy, agree with everything. Just to clarify, some of these seem to be remains from a first version of the patch in the PR that used USE_GITHUB although there is a proper distfile ;)

[jbo]

Update Makefile as requested.

However, unless I am being blind, the distfile does not include
a license file suitable for LICENSE_FILE?

[jbo]

Found the license file... sorry for the noise :D
