 Usage: complete [<cword> <word>...]
 
-In the first form, the command prints all possible completions to stdout.
-This can be used from the completion function of the shell.
+When executed without argument the command writes bash code to
+stdout. This code is suitable to be evaled from .bashrc to enable
+completion.
 
-Completion code suitable to be evaled is written to stdout if no argument
-was given.
+If at least one argument is given, all possible completions are
+written to stdout. This can be used from the completion function of
+the subcommand.
