+Notes on how to test tabix
+──────────────────────────
+
+The tabix package contains example data to test the tabix program. It is
+already compressed and indexed. The following instruction decompress,
+recompress, re-index and test the example data.
+
+# Create a temporary file
+TABIXDATA=$(mktemp)
+
+# Uncompress example data
+zcat /usr/share/doc/tabix/examples/example.gtf.gz > $TABIXDATA
+
+# Compress example data with bgzip
+bgzip $TABIXDATA
+
+# Index with tabix
+tabix $TABIXDATA.gz
+
+# Extract with tabix the he features on chromosome 1 whose coordinates overlap
+# the interval 150,309–150,309.
+tabix $TABIXDATA.gz chr1:150309-150309 > $TABIXDATA.out
+
+# Reference result at the bottom of this file
+grep H\AVANA /usr/share/doc/tabix/README.test > $TABIXDATA.ref
+
+# No difference ?
+diff $TABIXDATA.ref $TABIXDATA.out
+
+# Clean
+rm $TABIXDATA.gz $TABIXDATA.gz.tbi $TABIXDATA.out $TABIXDATA.ref
