+
+=== another case study ===
+
+During the summer, I pushed a bit on my random walk with replacing CMT. as a case study, I focused on providing a trimmed down athena framework tailored for ROOT flat n-tuples analysis, which I called 'mana' (mini athena)
+
+First, I tried to familiarize myself with CMake, and this materialized with 'mana-ext', a set of CMakeFiles to build the externals for mana
+(boost, clhep, root,...)

+
+
+I must say, I wasn't totally impressed in the end with CMake as a development environment (at least for the part where one has to write
+these CMake fragments). the syntax is bulky, string processing is clunky,... of course I just gave it a couple of weeks, but still.
+
+then, I worked back on my waf-based source code, and this was much more pleasant (python, I guess.)
+
+ [https://bitbucket.org/binet/mana-core mana-core]
+
+the status of project is summarized in the README of that bitbucket, as well as in the presentation I gave last week to the atlas physics analysis tools (in attachment.)
+
+in a nutshell, one can build mana-core on linux and macosx with the system-wide installed dependencies, or on lxplus with a lcgcmt
+environment setup (mana should be able to pick up the correct libraries.)
+
+the compilation is 5x faster than with the special toplevel Makefile From Marco.
+
+the wscript files (which are the req-files equivalent of waf) are semi-automatically generated from the CMT requirement files, using the same technique than Pere's generator.
+
+the environment is not pushed in the user's shell but is instead available as a subshell properly configured and spawned via 
+
+ '$ ./waf shell'
+
+I plan to implement (after ACAT) the compilation of externals a-la-ExternalProject_Add to waf (for which there is already a skeleton in SVN) as well as proper packaging (ditto): src-pkg, bin-pkg, rpm and mac-bundle.
