1. Introduction

This User’s Guide describes several software tools that use the GNAT project facility to drive their behavior. GNAT projects are stored in text files with the extension .gpr, commonly called GPR files.

These GPR tools use a common facility, the GNAT Project Manager, that is fully described in GNAT Project Manager.

The main GPR tool is GPRbuild, a multi-language builder for systems organized into subsystems and libraries. This tool is described in Building with GPRbuild.

The other GPR tools are described in GPRbuild Companion Tools:

• GPRconfig

  A configuration project file generator (see Configuring with GPRconfig).

• GPRclean

  A tool to remove compilation artifacts created by GPRbuild (see Cleaning up with GPRclean).

• GPRinstall

  Executable and library installer using GPR files (see Installing with GPRinstall).

• GPRname

  Naming scheme generator (see Specifying a Naming Scheme with GPRname).

• GPRls

  Library browser (see The Library Browser GPRls).
