I think this is an interesting use-case. It would be very simple to handle it by |
| 41 |
introducing an additional file that the package manager would use to record the |
| 42 |
packages that are installed on trial-basis. This would make it possible to |
| 43 |
include these packages in dep-calculations, while still distinguishing them from |
| 44 |
packages that are in @world. Of course you can also fake it by creating a local |
| 45 |
virtual/trialware package (or possibly a @trialware group) of which you edit the |
| 46 |
deps, but this would be less convenient. For my personal workflow using -1 for |
| 47 |
trials is working well enough, atm. |
