Example calls to lasvalidate:

C:\lastools\bin> lasvalidate -i ..\data\*.las -oxml

and

C:\lastools\bin> lasvalidate -i ..\data\*.las -o ..\data\summary.xml

The source code compiles under Windows and Linux is available from
github at http://github.com/LASvalidator

mkdir LASvalidator
cd LASvalidator
git clone https://github.com/LASvalidator/LASread.git 
cd LASread 
make 
cd .. 
git clone https://github.com/LASvalidator/lasvalidate.git 
cd lasvalidate 
make 
cd bin 
lasvalidate -h

This is version 130916 of the LAS validator. Please contact
me at 'martin.isenburg@rapidlasso.com' if you disagree with
validation reports, want additional checks, or find bugs.

Supported Inputs:
  -i lidar.las
  -i lidar1.las lidar2.las lidar3.las
