When you execute "runmc" (which is a link to jrunmc bash script),
JRunMC.jar executable (located in "main/jrunmc") reads
executables located in "bin" directory and check their status ("idle" or "running").
Then JRunMC builds a database from the physics project files (RMC)
which are located in "archive" directory of the main installation RunMC
directory. Each *.rmc file is a gzipped user directory "proj".
This directory contains user files with physics calculations, thus files in
this directory can be modified.
To read information on each *.rmc file, JRunMC reads XML file "user-comment.xml'.
You can manually unzip *.rmc file and look what is inside. One RMC file
is always unzipped - the user directory "proj" - which corresponds to
the current user calculation.
