Antlr license

    Hi guys,
    

    Our antlr package has "Public Domain" in the License tag. 
      However the author does add some conditions for credit being
      given, headers in source files be kept, etc. Please see the
      LICENSE.txt  and  README.txt files.
    

    This is what probably caused SPDX to create a specific "license"
      denomination for this:
    

          ANTLR Software Rights Notice
          ANTLR-PD
        
      
    Note: There is no reference to this license or anything specific
      to Antlr in OSI.

    
    Although it is true that it is public domain, we need to make
      sure his credit and header conditions are met.
    

    Should we add an Antlr license to our table and change the
      package to use it on the next update?

    
    Should we use the SPDX  "ANTLR Software Rights Notice" and as
      short name "ANTLR PD"?
    

    Or should we ignore all these details and just keep it as "Public
      Domain" ?

      SOFTWARE RIGHTS

      
      ANTLR 1989-2006 Developed by Terence Parr

      Partially supported by University of San Francisco & jGuru.com

      
      We reserve no legal rights to the ANTLR--it is fully in the

      public domain. An individual or company may do whatever

      they wish with source code distributed with ANTLR or the

      code generated by ANTLR, including the incorporation of

      ANTLR, or its output, into commerical software.

      
      We encourage users to develop software with ANTLR. However,

      we do ask that credit is given to us for developing

      ANTLR. By "credit", we mean that if you use ANTLR or

      incorporate any source code into one of your programs

      (commercial product, research project, or otherwise) that

      you acknowledge this fact somewhere in the documentation,

      research report, etc... If you like ANTLR and have

      developed a nice tool with the output, please mention that

      you developed it using ANTLR. In addition, we ask that the

      headers remain intact in our source code. As long as these

      guidelines are kept, we expect to continue enhancing this

      system and expect to make other tools available as they are

      completed.
