3 # ---------------------------
4 #
5 # This module configures and installs pkg-config scripts and the
6 # geant4-config program to help clients compile and link against
7 # the Geant4 libraries.
8 #
9 # The geant4-config script provides an sh based interface to provide
10 # information on the Geant4 installation, including installation prefix,
11 # version number, compiler and linker flags.
12 #
13 # The script is generated from a template file and then installed to the
14 # known bindir as an executable.
15 #
16 # Paths are always hardcoded in the build tree version as this is never
17 # intended to be relocatable.
18 # The Install Tree script uses self-location based on that in
19 # {root,clhep}-config is the install itself is relocatable, otherwise
20 # absolute paths are encoded.
