 The \module{shlex} module defines the following functions:
 
-\begin{funcdesc}{split}{s\optional{, comments}}
+\begin{funcdesc}{split}{s\optional{, comments\optional{, posix}}}
 Split the string \var{s} using shell-like syntax. If \var{comments} is
 \constant{False} (the default), the parsing of comments in the given
 string will be disabled (setting the \member{commenters} member of the
 \class{shlex} instance to the empty string).  This function operates
