Hi, > No one uses our RFC-2822-style thing except us, and no one has tools for it Well, then they should just apt install them. I failed to understand SPDX until today (with the exception of the license specifiers), which is mostly due to the quadrillion different formats SPDX data can come in. I am totally for aligning the License: field with SPDX licence specifications, but that's it. For everything else, SPDX is a PITA. -nik
