.IX Header "DESCRIPTION"
DBIx::Recordset::FileSeq generates unique numbers. State is kept in the
filesystem. With the new constructor you specify the directory
where the state is kept. (First parameter is a dummy values, that will
receive the database handle from DBIx::Recordset, but you don't need it
when you use it without DBIx::Recordset). Optionaly you can give a min and
a max values, which will be used for new sequences.
.PP
With \fBNextVal\fR you can get the next value
for the sequence of the given name.
.PP
The state if kept by haveing a file with the name
.PP
seq.<seqencename>.<max>.<count>
.PP
Each time the sequnce value increments the file is renamed. If the <max>
if a numeric value the new value is checked against <max> and NextVal
dies if the sequnce value increment above max.
