# This list contains licenses explicitly considered "free" by the Debian Free Software Guidelines (DFSG)
# It is manually curated, based on information found on these websites:
#  https://www.debian.org/legal/licenses/
#  https://wiki.debian.org/DFSGLicenses
# This list is very much incomplete and serves as "manual update" for the license lists automatically generated
# from FSF and OSI data, as some licenses are DFSG-free but have not yet been looked at by OSI/FSF (and we still
# want to count these licenses as free).
