102 | Usage: ${0##*/} [<options>] <GL implementation> |
103 | Set the opengl implementation. |
104 | Valid options: |
105 | --use-old: If an implementation is already set, use that one. |
106 | --prefix=<val>: Set the source prefix (default: /usr) |
107 | --dst-prefix=<val>: Set the destination prefix (default: /usr) |
108 | --impl-headers: Use headers provided by this implementation to |
109 | override global ones provided by opengl-update. |
110 | |
111 | Usage: ${0##*/} --get-implementation |
112 | Print the current implementaion |

114 | Notes: |
115 | --impl-headers was default in <opengl-update-2.2. |

122 | This will setup things to use libGL.so from X.org. |
123 | |
124 | ${0##*/} nvidia |
