The License datatype. For more information about these and other
open-source licenses, you may visit http://www.opensource.org/.
I am not a lawyer, but as a general guideline, most Haskell
software seems to be released under a BSD3 license, which is very
open and free. If you don't want to restrict the use of your
software or its source code, use BSD3 or PublicDomain.
|This datatype indicates the license under which your package is
released. It is also wise to add your license to each source file.
The AllRightsReserved constructor is not actually a license, but
states that you are not giving anyone else a license to use or
distribute your work. The comments below are general guidelines.
Please read the licenses themselves and consult a lawyer if you are
unsure of your rights to release the software.
|GPL||GNU Public License. Source code must accompany alterations.
|LGPL||Lesser GPL, Less restrictive than GPL, useful for libraries.
|BSD3||3-clause BSD license, newer, no advertising clause. Very free license.
|BSD4||4-clause BSD license, older, with advertising clause.
|PublicDomain||Holder makes no claim to ownership, least restrictive license.
|AllRightsReserved||No rights are granted to others. Undistributable. Most restrictive.
|OtherLicense||Some other license.
