Hi Phil: The list of device drivers in cmake/modules/drivers-init.cmake should be able to help you figure out the status of any of our devices. A typical entry in that list is a colon-separated string such as "svgcairo:cairo:ON:F:ON" where the first quantity is the device, the second quantity is the device driver, the third quantity (ON of OFF) specifies whether the device is enabled by default or not, the fourth quantity (F or I) specifies whether the device is a file device or an interactive device, and the fifth quantity (ON or OFF) specifies whether the device is familied or not. The overall status of any device is either completely retired (not mentioned on the list or commented out), disabled by default, or enabled by default. In the plmeta device driver case, we have the following details: # (2007-09-01) As discussed on list, don't enable plmeta until we sort # out the known issues (e.g., strings, aspect ratio, and TrueType fonts). # This is going to take time/energy for some volunteer who has not volunteered # yet.... :-) "plmeta:plmeta:OFF:F:OFF" so it is disabled by default which means default testing like mine never tests the device but, in principle, all a user has to do to try it out again is simply specify the cmake command-line option -DPLD_plmeta=ON to override the default -DPLD_plmeta=OFF that is generated by that entry in the list. > Also is there an easy way to read a plplot metafile in again?

That is what the utils/plrender utility does which (see utils/CMakeLists.txt) should be automatically built whenever -DPLD_plmeta=ON. As far as I know, nobody has tried out plmeta and plrender for a long time here. So please let us know your experiences with them. Alan __________________________ Alan W.
