1. Is it possible to define pseudo hyperlinks which start a subprocess?
That would be really phantastic because it allows for nice tutorials with
trial buttons. On xcf.berkely.edu I saw:

About XMap ...

<P>
Click here for a demo.
<S>/*script*/
if (accessible("/usr/users/ftp") != "") {
print("doing /usr/users/ftp/ftp_public/misc/ht/projects/xmap/ultrix.ws.2.1 /usr/users/ftp/ftp_public/misc/ht/projects/xmap/sf_oak &amp \n");
/* system("/usr/users/ftp/ftp_public/misc/ht/projects/xmap/ultrix.ws.2.1 /usr/users/ftp/ftp_public/misc/ht/projects/xmap/sf_oak &amp ");*/
} else if (accessible("/map" != "")) {
/* in case this is running in xcfdemo */
print("doing /xmap/ultrix.ws.2.1 /xmap/sf_oak &amp \n");
/* system("/xmap/ultrix.ws.2.1 /xmap/sf_oak &amp ");*/
} else {
/* can't guess where xmap executables might be */
bell(); /* later, use dialogbox */
}
</S>

Unfortunately it doesn't work, in Viola no button was shown.
