The \CompHEP~ root directory is not intended to start  a session.
For this  purpose  the user has to prepare a special  working directory. 
A few working directories may be created for  various tasks and by different
users. 

To prepare a working directory for 
processing  execute make command from within \CompHEP~ root directory:\\
\hspace*{2cm} {\tt make setup WDIR=path\_to\_your\_working\_dir }\\

Let the myWDIR is a name of a working directory. Let it in the root of user 
home directory. So, the make commad should be
following: \\
\hspace*{2cm} {\tt make setup WDIR=\$HOME/myWDIR } \\

Note, that you should not use \~ in the path to the working directory. Use
\$HOME environment variable insted of.

As a result  the  directory myWDIR and following sub-directories 
appear in your {\it myWDIR} directory:\\
\hspace*{2cm} {\tt models/~~~   tmp/~~~~~~~  results/}\\
\hspace*{2cm} {\tt usr/}

These directories contain some auxialiary files that are used by CopHEP during
the work. Please do not remove them if you are not sure.

The directory   {\it models} is used for  files which describe models 
of particle interactions. The directory  {\it tmp} is created for temporal
files.  The directory {\it results} is  assigned for a \CompHEP~ output. 
The directory {\it usr} contain template for user define function (see 
\ref{user-prg}"User programs in \CompHEP"  section for details).

 To start a \CompHEP~ session  you should issue a command\\
\hspace*{2cm}{\tt  ./comphep}

 The {\it comphep.ini} file allows  to choose an 
appropriate text font for the \CompHEP~ window, select the  color or colorless
mode for the window and also switch on/off the sound signal. The syntax of  
this file is self-explanatory.
