* If you only need a new version of a single package, such as nugen, then simply checkout that package, edit, tag and build.

* If you want a complete nulite distribution with the new package, then you would also checkout nutools and follow the instructions for updating the nu suite.

These instructions presume that the work is done on scisoftbuild01.fnal.gov.  These instructions also presume that the head of develop will be used.  If the tag will be made on a branch, refer to the NOvA instructions.

h3(count).  update "third party" products
35 14 Lynn Garren
36 15 Lynn Garren
Before building the nu suite, new releases of "third party" products need to be available.  Our definition of "third party products" is any product that does not use cetbuildtools or cetmodules.
37 15 Lynn Garren

This example updates the nu suite to use art 3.04.00.  python3 is the default. This means that the py3 qualifier is no longer used.  Instead, the py2 qualifier is used to specify a build with python v2_7_15a.  Because of this change, root has been updated to v6_18_04c.  Many products in the nulite distribution will need new releases with updated table files.

Create a temporary release branch.  This workflow mimics, but does not use, gitflow.  This allows us more flexibility when dealing with multiple repositories.

101 5 Lynn Garren
** Edit the package version and the nudist version in nutools/bundle/CMakeLists.txt.
102 5 Lynn Garren
** The nudist version must be the same as the nutools version, but with an alphabet character added to the end.
103 5 Lynn Garren
*** For instance, v3_01_03 would become v3_01_03a, v3_01_03b would become v3_01_03c, etc.
104 5 Lynn Garren
** Build nutools and use the generated nutools/bundle/nu* files. (See below for more information.)
