What you request can be readily achieved with ordinary scripting methods.
For example, this Perl script:
```
# /usr/bin/perl
my $nClump = shift;
if (!defined($nClump)) { $nClump = 100; }
print "BEGIN TRANSACTION;\n";
my $nLines = 0;
while ($_ = <>) {
print $_;
if (++$nLines % $nClump == 0) {
print "COMMIT TRANSACTION;\n";
print "BEGIN TRANSACTION;\n";
}
}
print "COMMIT TRANSACTION;\n";
```
in a file marked executable, "transact_clump", can be used thusly:
```
echo .quit | sqlite3 -batch -cmd ".mode insert People" -cmd "select * from People;" furd.sdb | transact_clump 5
```
to break a long sequence of inserts into clumps of inserts within transactions.
