Otherwise, describe the license in a precise and concise way, avoiding
ambiguous names such as +BSD+ which actually name a family of licenses.
This variable is optional. If it is not defined, +unknown+ will appear in
the +license+ field of the manifest file for this package.
the +license+ field of the manifest file for this package. +
The expected format for this variable must comply with the following rules:
** If different parts of the package are released under different
licenses, then +comma+ separate licenses (e.g. +`LIBFOO_LICENSE =
GPLv2+, LGPLv2.1+`+). If there is clear distinction between which
component is licensed under what license, then annotate the license
with that component, between parenthesis (e.g. +`LIBFOO_LICENSE =
GPLv2+ (programs), LGPLv2.1+ (libraries)`+).
** If the package is dual licensed, then separate licenses with the
+or+ keyword (e.g. +`LIBFOO_LICENSE = AFLv2.1 or GPLv2+`+).
* +LIBFOO_LICENSE_FILES+ is a space-separated list of files in the package
tarball that contain the license(s) under which the package is released.
