C4::Bookseller - Koha functions for dealing with booksellers.
=head1 SYNOPSIS
use C4::Bookseller;
=head1 DESCRIPTION
The functions in this module deal with booksellers. They allow to
add a new bookseller, to modify it or to get some informations around
a bookseller.
=head1 FUNCTIONS
=head2 GetBookSeller
@results = &GetBookSeller($searchstring);
Looks up a book seller. C<$searchstring> may be either a book seller
ID, or a string to look for in the book seller's name.
C<@results> is an array of references-to-hash, whose keys are the fields of of the
aqbooksellers table in the Koha database.

# FIXME: This function is badly named. It should be something like
# SearchBookSellersByName. It is NOT a singular return value.

# count how many baskets this bookseller has.
# if it has none, the bookseller can be deleted

=head2 AddBookseller
$id = &AddBookseller($bookseller);
Creates a new bookseller. C<$bookseller> is a reference-to-hash whose
keys are the fields of the aqbooksellers table in the Koha database.
All fields must be present.
Returns the ID of the newly-created bookseller.

=head2 ModBookseller
&ModBookseller($bookseller);
Updates the information for a given bookseller. C<$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<&booksellers>, modify what's necessary, then call
C<&ModSupplier> with the result.
