Flair version numbering, consists of 3 numbers starting from 0, in the form: flair-M.m-R
The About Dialog of the program displays the Major and minor version as well
the SVN release number, every time changes in the program are committed to the
SVN server. It is recommended the user to pay attention on the date of the last
change as well the date when the program is uploaded on the web site.
- M: Major version, this number is increased by one only when a major
modification in the structure of the program takes place. During the initial
phase of development is 0.
- m: Minor version, this number is increased by one every time a
addition in the program functionality is made. e.g. Adding new plotting forms,
mechanism, databases etc.
- R: Release, this number is increased every time when bug fixes take

The recommended way of installation is the use of rpm. The rpm installer,
will install the program in the /usr/local/flair directory and the
executable launcher programs in the /usr/local/bin. It will also create all
the necessary files and modify the system database to add the program in
the educational/science/physics menu, define the appropriate file
associations for the file types .flair, .fluka and .inp.
In case your system doesn't support the rpm, use the tar gzip file and
follow the instructions in the README file. For specialised help on various
OS, look first the FAQ.
In brief, expand the archive to a directory of your choice, and
either add it to the PATH variable or create an alias in your login script
||Script to launch jobs on a cluster using OpenPBS system. Can easily be modified for
other batch systems
