# Installation instructions
# -------------------------
#
# To install the library use target install
#
# To instell the library together with the doxygen documentation,
# use target all. Note that this requires doxygen to be installed.
#
# Look at gsexx_write_example.cc for a brief example on using the code.
#
# The binary library libgsexx.a will be placed in $(LOCLIBDIR). The prototype
# file gsexx.h will be linked to a copy in $(LOCINCLUDEDIR). If these 
# variables are not set in your environment, they will be set to reasonable
# values below. Please check.
#
# The doxygen documentation will be placed in $(DOXYWWWPATH). In case
# $(LOCLIBDIR) is not set in your environment, this will be set to a default
# value too.
#
# The library code itself depends only on common system libraries.
#

# If you launch "make doxydoc" the documentation will be written to
