Updates the information for a given bookseller. C<$bookseller> is a

reference-to-hash whose keys are the fields of the aqbooksellers table

in the Koha database. It must contain entries for all of the fields.

|
The entry to modify is determined by C<$bookseller-E<gt>{id}>.
|
|
|

The easiest way to get all of the necessary fields is to look up a

|
book seller with C<&GetBookseller>, modify what's necessary, then call
|
|
C<&ModBookseller> with the result.
