2.1 Download
</H2>

<P>
Presently, Q<SMALL>UANTUM </SMALL>ESPRESSO is distributed in source form; some precompiled
executables (binary files) are provided for <TT>PWgui</TT>.
Packages for the Debian Linux distribution are however
made available by <TT>debichem</TT> developers.
Stable releases of the Q<SMALL>UANTUM </SMALL>ESPRESSO source package (current version
is 6.0) can be downloaded from the Download section
of <TT>www.quantum-espresso.org</TT>.

<P>
Uncompress and unpack the base distribution using the command:
<PRE>
     tar zxvf espresso-X.Y.Z.tar.gz
</PRE>
(a hyphen before "zxvf" is optional) where <TT>X.Y.Z</TT> stands for the
version number. If your version of <TT>tar</TT>
doesn't recognize the "z" flag:
<PRE>
     gunzip -c espresso-X.Y.Z.tar.gz | tar xvf -
</PRE>
A directory <TT>espresso-X.Y.Z/</TT> will be created.

<P>
Additional packages that are not included in the base distribution
will be downloaded on demand at compile time, using <TT>make</TT>
(see Sec.<A HREF="node12.html#SubSec:Compilation">2.5</A>).
Note however that this will work only if the computer you are
installing on is directly connected to the internet and has
either <TT>wget</TT> or <TT>curl</TT> installed and working.
If you run into trouble, manually download each required package
into subdirectory <TT>archive/</TT>, <EM>not unpacking or
uncompressing it</EM>:
command <TT>make</TT> will take care of this during installation.

<P>
Package <TT>GWL</TT> needs a manual download and installation:
please follow the instructions given at <TT>gww.qe-forge.org</TT>.

<P>
The Q<SMALL>UANTUM </SMALL>ESPRESSO distribution contains several directories. Some of them are
common to all packages:

<P>
<TABLE CELLPADDING=3>
<TR><TD ALIGN="LEFT"><TT>Modules/</TT></TD>
<TD ALIGN="LEFT">fortran modules and utilities used by all programs</TD>

</TABLE>

while others are specific to a single package:

<TR><TD ALIGN="LEFT"><TT>GUI/</TT></TD>
<TD ALIGN="LEFT"><TT>PWGui</TT> package</TD>
</TR>
</TABLE>

<P>
Finally, directory <TT>COUPLE/</TT> contains code and documentation
that is useful to call Q<SMALL>UANTUM </SMALL>ESPRESSO programs from external codes; directory
<TT>LR_Modules/</TT> contains source files for modules that are common
to all linear-response codes.
