Releasing IMAS AL and IMAS libs when new DD version (x.y.z)  occurs

1. IMAS AL

Release new version of IMAS AL (described on other pages)

2. imasenv/x.y.z

1. Check, in which dir imasenv  modules are stored

   ~>module show imasenv
   -------------------------------------------------------------------
   /path/to/imasenv/a.b.c/:

2. cd  /path/to/imasenv/ 
3. cp -r a.b.c x.y.z-alpha
   1.  Assumption: a.b.c is (so far) the latest version of imasenv
   2. Version x.y.z will be (until all libraries will be ready) marked as -alpha to warn the users that it is "under construction"
4. cd x.y.z-alpha 

5. Contents of x.y.z-alpha dir: 

   x.y.z-alpha>ls -la
   drwxr-xr-x  gcc
   drwxr-xr-x  intel
   lrwxr-xr-x  rc -> intel/17.0/rc		# link to default module imasenv/x.y.z/rc
   -rw-r--r--  .version				# definition of default compiler of imasenv/x.y.z

   x.y.z-alpha>cat .version
   #%Module######################################################################
   # Default version
   set ModulesVersion  intel

6. Updating of imasenv module content

   1. all files x.y.z-alpha/<compiler>/<version>/rc (e.g. 3.26.0-alpha/gcc/7.3.0/rc) needs to be updated (rc is always the first published version, tagged on user demand)}}

   2. open these file using any editor

   3. updating IMAS AL versions 

      set imas_version x.y.z
      set al_version   a.b.c  

   4. Update all "submodules" versions (if needed/requested)
7. imasenv  module is updated, but when loading, it reports several errors - no lib compiled for new DD versions are available - to compile them - see next point

3. Updating of IMAS libraries

3.1. DD dependent vs independent libraries

1. There are two kinds of IMAS libraries:
   1. DD independent: BLAS, LAPACK, INTERPOS, XMLLIB . 
   2. DD dependent: GGD, LIBBDS, AMNS
2. BLAS/LAPACK have to be installed only if there are no system-wide ones available 
3. DD independent libraries don't have to be re-installed after DD update but only if users requests a new version
4. DD dependent libraries needs to be re-installed after every DD update/change

3.2. Installation scripts
