forked from mirrors/stickerpicker
78fdb6f175
The license was initially MPLv2 as I expected the project to be a fairly simple tiny web app, but it has already grown into multiple files. Now that I'm going to add a server component, I'm switching the license for future versions to AGPL like all my other non-library projects.
