web2c: Legalisms

 
 Appendix A Legalisms
 ********************
 
 In general, each file has its own copyright notice stating the copying
 permissions for that file.  Following is a summary.
 
    The Web2c system itself and most of the original WEB source files are
 public domain.
 
    'tex.web', the MLTeX code, 'mf.web', and 'bibtex.web', are
 copyrighted by their authors.  They may be copied verbatim, but may be
 modified only through a '.ch' file.
 
    MetaPost-related files, including 'mp.web' itself, are copyrighted
 under X-like terms; the precise notice is included below.
 
    Finally, the Kpathsea library is covered by the GNU Lesser General
 Public License (See(kpathsea)Introduction).  Therefore, the
 _binaries_ resulting from a standard Web2c compilation are also covered
 by the LGPL; so if you (re)distribute the binaries, you must also (offer
 to) distribute the complete source that went into those binaries.  See
 the file 'LGPL' for complete details on the LGPL.
 
    The following notice must be included by the terms of the MetaPost
