You have to do:

o make
o copy mod_gsweb.so in apache libexec (the apache directory of modules, in which you should have mod_mime.so, mod_alias.so,...)
o edit your apache configuration file:

	- Add 

        LoadModule GSWeb_Module  libexec/mod_gsweb.so
        AddModule mod_gsweb.c

	- Add Global configuration directives:
		o gsweb configuration file path
			GSWeb_ConfigFilePath /etc/httpd/conf/gsweb.conf		(for exemple)
		o gsweb alias
			GSWeb_Alias /GSWeb									(for exemple)

    - Add the following lines for a virtual host (or all hosts)
        <Location /GSWeb*>
                SetHandler GSWeb
        </Location>

o create your gsweb configuration file (see ../Doc/ConfigurationFile.html)
