      loksh is a Linux port of OpenBSD's ksh.

      Unlike other ports of ksh, loksh targets only one platform, follows
      upstream closely and keeps changes to a minimum. loksh does not add any
      extra features; this reduces the risk of introducing security
      vulnerabilities and makes loksh a good fit for resource-constrained
      systems.
