## library of table of marks.
## It is a record with the following components.

## <F>pkg/tomlib/data</F> and without the suffix <C>.tom</C>,

## <Item>
## list whose <M>i</M>-th entry corresponds to the <M>i</M>-th entry
## of the <C>files</C> component and is itself a list of identifier
## information about the tables of marks stored in this file;
## for each table of marks, the list of admissible identifiers is stored,
## with first entry the identifier that is used in the data file;
## note that some tables may be not actually installed, see the component
## <C>noninstalled</C> below,
## </Item>
## <Mark><C>names</C></Mark>
## <Item>
## list of admissible identifiers of tables of marks that are stored
## in files that are actually available,
## </Item>
## <Mark><C>noninstalled</C></Mark>
## <Item>
## list of admissible identifiers of tables of marks that are stored
## in files that are not available,

## <Item>
## list of pairs, the value <M>[ i, j ]</M> at position <M>k</M> means
## that the table of marks with admissible identifier the <M>k</M>-th

## where <A>id</A> is the identifiers of a table of marks of a subgroup
## such that the fusion into the current table of marks is known
## (in the sense of a calls of <Ref Func="ALFT"/>),
## and <A>nr</A> is the number of the class of these subgroups in the
## current table of marks.
