surf vs surf-alggeo

[ren]

The visualization package 'surf' has been included in the repository of Debian and Ubuntu under the name 'surf-alggeo':

​https://packages.debian.org/sid/math/surf-alggeo ​https://launchpad.net/ubuntu/+source/surf-alggeo

It would be good if surf.lib would be able to find out whether to call 'surf' or 'surf-alggeo'. Under Linux, this could be done with:

string surfCommand;
proc mod_init()
{
  string pathToSurf = getShellOutput("command -v surf-alggeo");
  surfCommand = pathToSurt[size(pathToSurf)-10..size(pathToSurf)];
  if (surfCommand != "surf-alggeo")
  {
    surfCommand = "surf";
  }
}

Not sure how to a solution would look like that would also work under Windows and MacOs?.

It would be easier (and faster) to use

string surfCommand=system("executable","surf-alggeom");
if (surfCommand==""){ surfCommand=system("executable","surf");}
if (surfCommand=="") {ERROR("surf not found");}
