Making new linux (lark) test tree dtacqtest

1-2) Make a test directory and tell MDSplus about it

    Edit /etc/mdsplus.conf to define new path:
    
     dtacqtest_path    /u/roney/dtacqtest
     
   (normal procedure is to make dated backup first; I also
    make mdsplus.conftemp, edit mdsplus.conftemp, do a
    differences between mdsplus.conf and mdsplus.conftemp,
    then copy mdsplus.conftemp on top of mdsplus.conf; this
    is intended to have mdsplus.conf be in a valid state at
    all times, since it is executed by every login, including
    remote mdsip logins)
    
3) Create shell for new model tree:

    mdstcl
    edit/new dtacqtest
    write
    exit
    
4) Use Traverser or MDStcl script to populate tree as desired

5) If tree is to be visible from portal/nstxpool, edit

   /p/nstxusr1/util/modulefiles/nstxtreedefs, first putting
   backup copy in modulesbk
   
        setenv mse_path           "lark.pppl.gov:8501::"

   when finished, copy nstxtreedefs to 
   /usr/pppl/Modules/modulefiles/nstx/treedefs
   
   (note difference in name)
   
   then module unload nstx/treedefs and
        module load nstx/treedefs
	
   to make definition take effect
   
6) If tree is to be visible from VMS, edit COM$MGR:COMSYSLNM.COM

    $ define/system/$ !  21-Nov-2003 PR   Added defn of mse tree (on lark) for MDSplus
    $ DEFINE/NOLOG/SYSTEM   MSE$DATA      lark.pppl.gov:8501::
    
    VMS logical is <treename>$DATA where linux environment variable is 
    <treename>_path
    
7) If/when tree becomes a production tree, add a structure node to tree
   larknstx with the tree's name, and then "set node/subtree <treename>"
