Re: [ESPResSo] polymer command

[Torsten Stuehn]

Hi all,

the polymer command has been fixed. The density of bond vectors is now
uniformly distributed ( OLD_RW_VERSION in myconfig.h has to be undefined ).
Currently only the CVS version has been fixed but there will be a new
ESPResSo release soon.

Greetings,
Torsten.
