19 | ?S: This variable holds a list of all extensions (both XS and non-xs) |
20 | ?S: included in the package source distribution. This information is | |
21 | ?S: only really of use during the Perl build, as the list makes no | |
22 | ?S: distinction between extensions which were build and installed, and | |
23 | ?S: those which where not. See "extensions" for the list of extensions | |
24 | ?S: actually built and available. | |

26 | ?S:dynamic_ext: | |
27 | ?S: This variable holds a list of XS extension files we want to | |
28 | ?S: link dynamically into the package. It is used by Makefile. | |

75b514d0 MBT |
35 | ?S: This variable holds a list of all non-xs extensions built and |
36 | ?S: installed by the package. By default, all non-xs extensions | |
37 | ?S: distributed will be built, with the exception of platform-specific | |
38 | ?S: extensions (currently only one VMS specific extension). | |

41 | ?S: This variable holds a list of all extension files (both XS and | |
75b514d0 | 42 | ?S: non-xs) installed with the package. It is propagated to Config.pm |
4dd7201d | 43 | ?S: and is typically used to test whether a particular extension |

47 | ?S: This variable holds either 'true' or 'false' to indicate | |
48 | ?S: whether the POSIX extension should be used. The sole | |
49 | ?S: use for this currently is to allow an easy mechanism | |
50 | ?S: for hints files to indicate that POSIX will not compile | |
51 | ?S: on a particular system. | |

55 | ?S: whether the Opcode extension should be used. The sole | |
56 | ?S: use for this currently is to allow an easy mechanism | |
