2. GLAST LAT Offline SoftwareWorkshop - SLAC, Jan. 16-19, 2001 T. Lindner2 User Support –Over the past couple months we’ve been improving user support. Couple specific points: Added to our online documentation on the main Glast Software page. http://www-glast.slac.stanford.edu/software/ Simplified the process of checking out and building the code by 1.increasing the use of checkout packages 2.collecting the external libraries in one place Worked on ways of implementing our use of doxygen.

3. GLAST LAT Offline SoftwareWorkshop - SLAC, Jan. 16-19, 2001 T. Lindner3 Online Documentation –We’ve been increasing and improving the online software documentation. –In particular we’ve added a How-To page http://www- glast.slac.stanford.edu/software/CodeHowTo/ http://www- glast.slac.stanford.edu/software/CodeHowTo/ –This page explains the important concepts and commands in cvs and CMT. –It also covers how these commands are used to build, run and develop CMT packages.

4. GLAST LAT Offline SoftwareWorkshop - SLAC, Jan. 16-19, 2001 T. Lindner4 Checkout Packages –One drawback to CMT is that it isn’t always clear which versions of which packages are meant to be used together. –Our solution has been to define checkout packages: these are simply packages in which the versions of all dependent packages are defined. –Added a page that lists all the checkout packages http://www.slac.stanford.edu/exp/glast/ground/softw are/LatestPackages/index.htm –The page gets updated nightly by a perl script.

5. GLAST LAT Offline SoftwareWorkshop - SLAC, Jan. 16-19, 2001 T. Lindner5 External Libraries –We have also been rationalizing how external libraries are treated. –First, this involved ensuring that all necessary libraries, on all supported platforms, were available from the SLAC ftp site. –Second, we have implemented a more sensible method for CMT to find all these external libraries. This meant, principally, some reworking of the CMT package EXTLIB. –More info at http://www- glast.slac.stanford.edu/software/CodeHowTo/exter nal_libraries.htm

6. GLAST LAT Offline SoftwareWorkshop - SLAC, Jan. 16-19, 2001 T. Lindner6 Documentation (Doxygen) We’ve been working on implementing our use of doxygen. –Doxygen-style comments have been included in the new packages which use Gaudi. –VCMT will now create the doxygen documentation for a package.

7. GLAST LAT Offline SoftwareWorkshop - SLAC, Jan. 16-19, 2001 T. Lindner7 Doxygen (cont’d) –We also have a script that produces doxygen documentation for a complete checkout set. –You can see examples of this documentation at http://www- glast.slac.stanford.edu/software/CodeHowTo/doxy gen_documentation.htm –A page (of the How-To page) describes the suggested use of doxygen.

8. GLAST LAT Offline SoftwareWorkshop - SLAC, Jan. 16-19, 2001 T. Lindner8 User Support (add.) The following pages will be of use to people having problems –People to Call http://www-glast.slac.stanford.edu/software/GlastBusters.htm –Trouble Shooting http://www- glast.slac.stanford.edu/software/CodeHowTo/TroubleShooting.htm –Gaudi FAQ http://www-glast.slac.stanford.edu/software/Gaudi/doc/faq.htm

9. GLAST LAT Offline SoftwareWorkshop - SLAC, Jan. 16-19, 2001 T. Lindner9 Platform Support –Much of the core development continues to be on Windows. –But we still support both Solaris and Linux. This should not prove too dificult as long as progress does not continue on one system for too long without testing the other systems. –Official releases will naturally be tested first on all three systems.
