# Common Makefile for creating FastR variants of the default packages
# The common part of the archive (everything except the .so) is created
# by copying the directory in the GnuR build. Then the FastR .so file is created
# and overwrites the default. The libraries are stored in the directory denoted
# FASTR_LIBRARY_DIR.

# A package that requires special processing before the library is built should
# define LIB_PKG_PRE and for post processing define LIB_PKG_POST in its Makefile.
# If a package-specfic clean is needed it should define CLEAN_PKG. PKG_INCLUDES can be
# used to define package-specific includes. XTRA_C_OBJECTS can be used to specify extra
# object files. PKG_LIBS can specify additional libraries required by the package.
# XTRA_C_OPTS and XTRA_F_OPTS can be used to specify additional C/Fortran compiler options.

# A package uses C_SOURCES_EXCLUDED and F_SOURCES_EXCLUDED to specify excluded C/Fortran 
# sources.

# If no library file is produced, a package sets NO_LIBRARY to 1.
