[Pw_forum] XML output

[carlo sbraccia]

Hi All,

an alternative possibility is downloading the CVS version of the code 
and compiling it with -D__NEWPUNCH. The resulting executable will 
produce a punch file ( outdir/prefix.save-new/restart.xml, but this name 
will change in the forthcoming stable version ) that is already in the 
XML format. Moreover this format is already kind of stable and is the 
one that will be used the next stable release. Note that the CVS version 
of the CP code already uses this format for its restart file.
