+"""
+Concatenate two bed files.  The concatenated files are returned in the
+same format as the first.  If --sameformat is specified, then all
+columns will be treated as the same, and all fields will be saved,
+although the output will be trimmed to match the primary input.  In
+addition, if --sameformat is specified, missing fields will be padded
+with a period(.).
+
+usage: %prog in_file_1 in_file_2 out_file
+    -1, --cols1=N,N,N,N: Columns for chrom, start, end, strand in first file
+    -2, --cols2=N,N,N,N: Columns for chrom, start, end, strand in second file
+    -s, --sameformat: All files are precisely the same format.
