|
|
* 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.
|
|
* <p>
|
|
* 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.
