Short: "Access Linux-native file system infrastructure (including LVM and LUKS) on macOS and Linux. Powered by a lightweight Alpine Linux VM and FTP.",
Long: `Linsk is a utility that allows you to access Linux-native file system infrastructure, including device mapping technologies like LVM and LUKS without compromise on other operating systems that have little ` +
`to no support for Linux's wide range of file systems, mainly aiming macOS and Windows. Linsk does not reimplement any file system. Instead, Linsk ` +
`utilizes a lightweight Alpine Linux VM to tap into the native Linux software ecosystem. The files are then exposed to the host via fast and widely-supported FTP, ` +
`operating at near-hardware speeds.`,
