/** \file builder.cpp
 *
 * By stating absolute positions or binding angles and distances atomic positions of a molecule can be constructed.
 * The output is the complete configuration file for PCP for direct use.
 * Features:
 * -# Atomic data is retrieved from a file, if not found requested and stored there for later re-use
 * -# step-by-step construction of the molecule beginning either at a centre of with a certain atom
 *
 */

/*! \mainpage Molecuilder - a molecular set builder
 *
 * This introductory shall briefly make aquainted with the program, helping in installing and a first run.
 *
 * \section about About the Program
 *
 *  Molecuilder is a short program, written in C++, that enables the construction of a coordinate set for the
 *  atoms making up an molecule by the successive statement of binding angles and distances and referencing to
 *  already constructed atoms.
 *
 *  A configuration file may be written that is compatible to the format used by PCP - a parallel Car-Parrinello
 *  molecular dynamics implementation.
 *
 * \section install Installation
 *
 *  Installation should without problems succeed as follows:
 *  -# ./configure (or: mkdir build;mkdir run;cd build; ../configure --bindir=../run)
 *  -# make
 *  -# make install
 *
 *  Further useful commands are
 *  -# make clean uninstall: deletes .o-files and removes executable from the given binary directory\n
 *  -# make doxygen-doc: Creates these html pages out of the documented source
 *
 * \section run Running
 *
 *  The program can be executed by running: ./molecuilder
 *
 *  Note, that it uses a database, called "elements.db", in the executable's directory. If the file is not found,
 *  it is created and any given data on elements of the periodic table will be stored therein and re-used on
 *  later re-execution.
 *
 * \section ref References
 *
 *  For the special configuration file format, see the documentation of pcp.
