I was analyzing the licensing situation in the lime-packages repository. There is no file that indicates the global license, there is no CLA (Contributor License Agreements) and there are copyright headers set in some files inconsistently. establish a license (such as GLPv3 or AGPLv3). This would affect future contributions, but it would be necessary for contributors to accept that their already written code is also licensed. To solve this situation I propose: * Set a license * Clarify that the contributions made in this repository respect that license. * Change existing headers and add missing ones. * Create a pull request with all these changes and approve the merge among all contributors as a form of acceptance.
