-NAME
-     catsh – a shell
-
-DESCRIPTION
-     catsh is a shell derived from FreeBSD sh(1), which is in turn derived
-     from Almquist shell.  It includes editline(3) from NetBSD.
-
-   Differences from sh(1)
-     •   ENV defaults to ‘${XDG_CONFIG_HOME:-${HOME}/.config}/catsh/env.sh’.
-
-     •   PS0 is printed before each prompt, allowing multi-line prompts.
-
-     •   Right-aligned prompts can be set with RPS1 and RPS2.
-
-     •   PSlit can be used to embed terminal escape sequences in prompts, as
-         in NetBSD sh(1).
-
-     •   HOME is shortened to ‘~’ in prompt expansion.
-
-     •   fc -s =new allows prefixing commands with new.
-
-HISTORY
-     sh(1) sources were imported from FreeBSD 12.0.  editline(3) sources were
-     imported from NetBSD 8.0.
