NAME

       ament_index - query the ROS 2 ament resource index

SYNOPSIS

       ament_index [resource-type] [resource-name]

DESCRIPTION

       ament_index is part of ROS 2, the Robot Operating System. The ament resource index is used
       to quickly query installed packages and some ROS system properties by reading  files  from
       well-defined locations.

RESOURCE INDEX

       The ament resource index is looked for in all prefixes which are listed in the environment
       variable AMENT_PREFIX_PATH and, for  Debian,  in  /usr,  unless  the  special  environment
       variable AMENT_PREFIX_NO_IMPLICIT_USR is set to a non-empty value.  The resource files can
       be found under

       share/ament_index/resource_index/resource-type/resource-name

                                                                                   AMENT_INDEX(1)
