 data exchange and processing.
 
 In order to build las2ogr utility, one has to link libLAS against GDAL library.
-For Unix, use ./configure script option --with-gdal.
-For Windows, edit nmake.opt file and set GDAL_HOME variable.
-Windows users can instal GDAL binaries using friendly installer from OSGeo4W package.
+See :ref:`compilation` for details on how to link against GDAL.

+.. note::
+    Windows users can install GDAL binaries using friendly installer from OSGeo4W package.

+
+lasblock is a utility for pre-processing an LAS file into "chips" or "blocks".  
+These blocks are a custom point partitioning process that aims to optimize 
+the fill capacity, shape, and speed of processing.  More specifically, 
+it attempts to keep the blocks as full as possible and as square as possible 
+to augment querying characteristics for `Oracle Point Cloud`_. 
+This pre-processing is needed as precursor 
+step in the processing chain that ends with actually loading the data via 
+:ref:`las2oci`.
+
+
+Usage
+------------------------------------------------------------------------------
+
+
+::
+
+    $ lasblock -c 3000 myfile.las
+
+.. note::
+    If no capacity is specified with ``-c``, 10000 is assumed.  
+
+.. note::
+    lasblock will always write out a myfile.las.kdx file name by default, 
+    but you can override the output name with a ``-o`` command-line switch.
