That is, they are distributed with it and are Free Software , but they are not considered essential parts of the distribution. Further, they may bear licenses other than the GPL or the FSF does not administer their copyrights. To determine their copyright status and licensing, see the "COPYRIGHT" file in the appropriate subdirectory of contrib/. Some files are part of groff but bear licenses in addition to the GPL, or have been placed into the public domain. This is because they originated elsewhere; often, the groff project has modified them, sometimes extensively. These multi-licensed groff components are as follows.
