[Ludovic Courtès]

Hi Greg,

Overall the patches LGTM.  Two minor issues:

  1. They were mangled on the way.  Could you send them as attachments
     or with ‘git send-email’ to this address?

  2. Could you improve descriptions?  In particular, please write full
     sentences, explain acronyms, and expound a bit as you see fit:

     https://guix.gnu.org/manual/en/html_node/Synopses-and-Descriptions.html

Could you send updated patches?

Thanks, and sorry for the delay!

Ludo’.

bug#43913: [PATCH 0/4] gnu: Add aws-sdk-cpp.

[Ludovic Courtès]

Hi Greg,

I pushed all four patches as commit
5686f5d7cdde6ba3149ef960149ff2ff323d49e2.  I modified a couple of issues
reported by ‘guix lint’ on the way, notably patch file names that were
too long.

Thanks!

Ludo’.
