This is the first public release of fully reentrant C
    scanners for the PHP language and the INI system.  They
    can be used to replace the Flex-based implementations
    commonly found in the Zend Engine.


    - Flexible I/O model; lays groundwork for fully supporting
      modern web-servers such as Apache 2.0;
    - uses portable C only; significantly improves portability by
      removing dependence on GNU extensions of C++;
    - fully thread-safe without loss of speed.

    The software is currently available in the form of three
    source files and a patch to the Zend Engine.

    To install, cd into the ngscan directory and run
    "make ZEND=../php4/Zend install", followed by a buildconf.

    Because software already exists to eliminate the scan/parse
    process, speed was not a main concern.  The new language
    scanner is faster than the old one in all tested scenarios
