48 | # It's actually a cut and shut of the Unix version ext/utils/makeext and the |

286d62c2 |
57 | # If '--static' is specified, static extensions will be built. |

58 | # If '--dynamic' is specified, dynamic extensions will be built. |
59 | # If '--nonxs' is specified, nonxs extensions will be built. |
281da5ea |
60 | # If '--dynaloader' is specificied, DynaLoader will be built. |

63 | # make_ext.pl "MAKE=make [-make_opts]" --dir=directory [--target=target] [--static|--dynamic|--all] +ext2 !ext1 |

67 | # make_ext.pl "MAKE=nmake -nologo" --dir=..\ext |

75 | # Will skip building extensions which are marked with an '!' char. |
76 | # Mostly because they still not ported to specified platform. |
77 | # |
78 | # If any extensions are listed with a '+' char then only those |
