# alibtool is added
#
#
# SYNOPSIS
# alibtool <command> <commandparameters>
#
# command must be one of the following:
#
#         mkmodule
#         depend
#         dependF
#
#
# DESCRIPTION
#
# This scipts is called with a primary command and a command parameter.
# It generates output on stdout, so normally it is called with a redirection,
# like:
#
#   alibtool mkmodule STEER > STEER/module.mk
#
# The command is one of the following:
#
# depend
#     Makes the dependencies for the file specified as second argument
#     (for c and cxx files)
#
# dependF
#     Makes the dependencies for the file specified as second argument
#     (for fortran files)
#
# mkmodule
#     Creates the module.mk for the the given directory specified as
#     the second argument
#
# MKMODULE
#
# 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 are made with rmkdepend.
#
#
# DEPENDF
#
# The same as depend, but for fortran files.
