3 idngram_merge - merge idngram file into one
7 B<idngram_merge> [I<option>]... I<idngram_file>...
11 B<idngram_merge> merge multiple idngram file, each of them are sorted
12 [id1,...,idN,freq] array, into one idngram file. For those id1..idN which
13 appear in more than one files, only one item will appear in the final file,
14 and its freq are summed. The idngram files are original generated by
18 All the following options are mandatory.
22 =item B<-n>, B<--NMax> I<N>
24 Specify the N-gram of source data file.
26 =item B<-o>, B<--out> I<output-file>
28 Specifiy the final merged idngram file.
35 Following example merge 2 id3gram files into a large one:
37 B<idngram_merge -n3 -o all.id3gram first.id3gram second.id3gram>
