== Availability == 

Version 1.0 of Larry3D is included in the 2.0 release of the [wiki:download SEATREE package].



== Requirements ==

A Fortran compiler, such as gfortran.

== Installation ==

Larry3D is installed automatically using the development version of the [http://geosys.usc.edu/projects/seatree/browser/trunk/configure SEATREE configuration and installation utility].

Larry3D can be installed manually by changing into the SEATREE subdirectory where larry3d resides, and typing "make".

== Documentation ==

Use of Larry within the Seatree environment is described in the [wiki:UserDocs Seatree user documentation].
