\modulesynopsis{Guess which DBM-style module created a given database.}
 | 
						|
 | 
						|
 | 
						|
The single function in this module attempts to guess which of the
 | 
						|
several simple database modules available--dbm, gdbm, or
 | 
						|
dbhash--should be used to open a given file.
 | 
						|
 | 
						|
\begin{funcdesc}{whichdb}{filename}
 | 
						|
Returns one of the following values: \code{None} if the file can't be
 | 
						|
opened because it's unreadable or doesn't exist; the empty string
 | 
						|
(\code{""}) if the file's format can't be guessed; or a string
 | 
						|
containing the required module name, such as \code{"dbm"} or
 | 
						|
\code{"gdbm"}.
 | 
						|
\end{funcdesc}
