+Underneath is a macro that opens a ''TBrowser'' and defines some usefull functions. It can be run using ''root myMacro.C'' or with a predefined function
+<code>
+function TBrowse { root -l "$@" ~/macros/myMacro.C; }
+</code>
+Run the function in the command line with ''TBrowse analysis.root''. To open all root files in the current directory: ''TBrowse *.root'', even quicker: ''TBrowse *t''.
