# alibtool is added
#
#
# SYNOPSIS
# alirun <command> <commandparameters>
#
# command must be one of the following:
#
#         mkmodule
#         depend
#         dependF
#
#
# DESCRIPTION
#
# This scipts is called with a primary command and a commandparameter. It generates output on stdout, so normally it is called with a redirection like
#
#   alibtool mkmoudle STEER > STEER/module.mk
#
# The command is one of the following
#
# depend
#        Makes the dependencies for the file specified as second argument (c and cxx files)
#
# dependF
#        Makes the dependencies for the file specified as second argument (fortran files)
#
# mkmoudle
#        Creates the module.mk for the the given directory specified as the second argument.
#
# MKMOUDLE
#
# When alibtool is called with the mkmodule command it searches the directory given as the second argument for files called *.pkg. If a file (possibly several) is found, it will create a file called module.mk based on these files. For example if running alibtool mkmodule STEER, it will search the STEER directory and create STEER/module.mk based on all .pkg files is STEER directory. If a file called libSTEER.pkg is found, then module.mk will have a section devoted to makeing library libSTEER.so with alle the sourcefiles specified in libSTEER.pkg. If a file called binSTEER.pkg is found the module.mk file will create an executable called STEER. Several *.pkg files can be placed in the same directory. The module.mk files is created on background of build/header.tpl and build/module.mk by variable substituion of variables @MODULE@ @PACKAGE@ and @TYPE@.
#
# PKG FILES
#
#
# The syntax for the pkg file is very simple. You specify the sources, headers and possibly extra include or link options. The *.pkg files is just inserted "as is" in the module.mk file, so normal Makefile syntax can be used. These variables can be specified: SRCS, FSRCS, CSRCS, HDRS, CHDRS, DHDR, EINCLUDE, ELIBS, ELIBSDIR, PACKFFLAGS, PACKCFLAGS, PACKCXXFLAGS. The first five is just the c++ sources, fortran sources, c sources, c++ headers and c headers. DHDR is the dictionary header and is the LinkDef file. EINCLUDE, ELIBS and ELIBSDIR is extra includedirs, libraries and library search paths. If for example a binary is to be linked against the variable ELIBSDIR would be set to lib/tgt_$ALICE_TARGET. Notice that -L and -l is not needed. If the PACKFFLAGS, PACKCFLAGS or PACKCXXFLAGS is not set it will be set to the default options (Set in config/Makefile.$ALICE_TARGET. For example on Linux GEANT321 has to be compiled without -O options, so a line like PACKFFLAGS := $(filter-out -O%,$(FFLAGS)) is needed.
#
#
# DEPEND
# 
# If alibtool is called with the depend command it will generate a dependecy file for the sourcefile given as second argument. This only goes for c++ and c files. If dependencies for fortran-fiels is needed, call alibtool with command dependF. The dependencies is made with rmkdepend.
#
#
# DEPENDF
#
# The same as depend, but for fortran files.
