+=head1 NAME
+
+splitTranscriptGff.pl - compare 2 input gff files and define utr and intergenic operonic intervalles by couple of overlapping elements
+
+=head1 SYNOPSIS
+
+% intervallsExtractorGff.pl -i referencies.gff -j transcriptQueries.gff -s strand [-h] 
+
+=head1 DESCRIPTION
+This script will intersect 2 gff files and compute distance between 2 successives lines. Take care both of sorting by positions the input files and of that referencies are included in transcriptQueries.
+
+    -i|--input1 fileName   gff input file name: included elements
+    -j|--input2 fileName   gff input file name: extended elements
+   [-s|--strand] [s|d]	   s for single strand (colinear) or d for double strands (antisense) [default d]
+   [-h|--help]             help mode then die                              
+
+=head1 USECASE
+Define many fragments for each extended element (transcript): UTR5, gene, UTR3, "inOperon" for intergenomic region between 2 genes
+intervallsExtractorGff.pl -i CDSannotations.gff -j RNAseqTranscripts.gff  > UTRsGenesOperonsLists.gff;
+
+=head1 KWON BUGS
+No disjonction of overlapping elements of the included elements (-i file).
+In usecase, overlapping genes are fused in one long gene.
