Healpy is GPL v2 because of HEALPIX being GPL v2, and importing is enough to make reproject GPL. This is really annoying because I was hoping to use reproject in APLpy but now I can't. There are two ways forward:\r\n\r\n* Ask the HEALPIX developers to re-release under LGPL, which I think solves this issue\r\n\r\n* Write out own implementation of HEALPIX which may not be so hard because we actually only use a very small fraction of the functionality in HEALPIX\r\n\r\n :hankey:"},"comment":{"url":"https://api.github.com/repos/astrofrog/reproject/issues/comments/100164245","html_url":"https://github.com/astrofrog/reproject/issues/82#issuecomment-100164245","issue_url":"https://api.github.com/repos/astrofrog/reproject/issues/82","id":100164245,"user":{"login":"cdeil","id":852409,"avatar_url":"https://avatars.githubusercontent.com/u/852409?v=3","gravatar_id":"","url":"https://api.github.com/users/cdeil","html_url":"https://github.com/cdeil","followers_url":"https://api.github.com/users/cdeil/followers","following_url":"https://api.github.com/users/cdeil/following{/other_user}","gists_url":"https://api.github.com/users/cdeil/gists{/gist_id}","starred_url":"https://api.github.com/users/cdeil/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/cdeil/subscriptions","organizations_url":"https://api.github.com/users/cdeil/orgs","repos_url":"https://api.github.com/users/cdeil/repos","events_url":"https://api.github.com/users/cdeil/events{/privacy}","received_events_url":"https://api.github.com/users/cdeil/received_events","type":"User","site_admin":false},"created_at":"2015-05-08T09:05:52Z","updated_at":"2015-05-08T09:05:52Z","body":"I've had this issue for Gammapy ... Sherpa is GPL at the moment (although that might change).\r\n\r\nAfter discussions with several people I'm not pretty sure that an optional GPL dependency (like healpy is for reproject) is OK for a BSD package (see [here](https://gammapy.readthedocs.org/en/latest/install.html#bsd-or-gpl-license)).\r\n\r\nNote that @taldcroft sees it the same way and e.g. also released https://github.com/taldcroft/datastack under BSD-3.\r\n\r\nSo maybe at least don't rush the license change to GPL for reproject / aplpy ... try to see if the current situation is OK or ask the HEALPIX / healpy guys to consider LGPL ..."}}
