17# This script generates PHP lexer and parser files required to build PHP. The
18# generated files are ignored in the Git repository and packaged during the PHP
19# release process into the release installation archive download. This way the
20# bison and re2c dependencies are not required to build PHP when downloading
21# release archive.
22#
23# Usage: genfiles
24#
25# Environment:
26#   The following environment variables can override default generators paths.
27#
28#     YACC    Parser generator program, default bison
29#     RE2C    Lexer generator program, default re2c
30#     SED     Path to sed program, default sed
31#     MAKE    Path to make program, default make
32#
33#   For example:
34#     YACC=/path/to/bison ./genfiles
