9 | There's also a companion library: libfuse2. This library is available |
| 10 | from the FUSE homepage: | |
| c1b0c627 | 11 | <https://github.com/libfuse/> |
| 807185eb RD |
12 | although chances are your distribution already has that library |
| 13 | installed if you've installed the "fuse" package itself. | |
