6.2 Ports with distribution restrictions

6.2.1 NO_PACKAGE

This variable indicates that we may not generate a binary package of the application. For instance, the license may disallow binary redistribution, or it may prohibit distribution of packages created from patched sources.

However, the port's DISTFILES may be freely mirrored on FTP/HTTP. They may also be distributed on a CD-ROM (or similar media) unless NO_CDROM is set as well.

NO_PACKAGE should also be used if the binary package is not generally useful, and the application should always be compiled from the source code. For example, if the application has configuration information that is site specific hard coded in to it at compile time, set NO_PACKAGE.

NO_PACKAGE should be set to a string describing the reason why the package should not be generated.

6.2.2 NO_CDROM

This variable alone indicates that, although we are allowed to generate binary packages, we may put neither those packages nor the port's DISTFILES onto a CD-ROM (or similar media) for resale. However, the binary packages and the port's DISTFILES will still be available via FTP/HTTP.

If this variable is set along with NO_PACKAGE, then only the port's DISTFILES will be available, and only via FTP/HTTP.

NO_CDROM should be set to a string describing the reason why the port cannot be redistributed on CD-ROM. For instance, this should be used if the port's license is for ``non-commercial'' use only.

6.2.3 RESTRICTED

Set this variable alone if the application's license permits neither mirroring the application's DISTFILES nor distributing the binary package in any way.

NO_CDROM or NO_PACKAGE should not be set along with RESTRICTED since the latter variable implies the former ones.

RESTRICTED should be set to a string describing the reason why the port cannot be redistributed. Typically, this indicates that the port contains proprietary software and that the user will need to manually download the DISTFILES, possibly after registering for the software or agreeing to accept the terms of an EULA.

6.2.4 RESTRICTED_FILES

When RESTRICTED or NO_CDROM is set, this variable defaults to ${DISTFILES} ${PATCHFILES}, otherwise it is empty. If only some of the distribution files are restricted, then set this variable to list them.

Note that the port committer should add an entry to /usr/ports/LEGAL for every listed distribution file, describing exactly what the restriction entails.
