+Merge two regions. Passing 'true' as the optional third parameter will force
+a merge ('force' merges regardless else merge will fail unless passed
+adjacent regions. 'force' is for expert use only).
+
+NOTE: You must pass the encoded region name, not the full region name so
+this command is a little different from other region operations.  The encoded
+region name is the hash suffix on region names: e.g. if the region name were
+TestTable,0094429456,1289497600452.527db22f95c8a9e0116f0cc13c680396. then
+the encoded region name portion is 527db22f95c8a9e0116f0cc13c680396
+
+Examples:
+
+  hbase> merge_region 'ENCODED_REGIONNAME', 'ENCODED_REGIONNAME'
+  hbase> merge_region 'ENCODED_REGIONNAME', 'ENCODED_REGIONNAME', true
+EOF
