+For the lf file manager configuration files (lfrc) the shell commands
+syntax highlighting can be changed globally and per buffer by setting
+a different 'include' command search pattern using these variables:
+ let g:lf_shell_syntax = "syntax/dosbatch.vim"
+ let b:lf_shell_syntax = "syntax/zsh.vim"
+
+These variables are unset by default.
+
+The default 'include' command search pattern is 'syntax/sh.vim'.
