New Revision: 25619
URL: http://svn.gna.org/viewcvs/relax?rev=25619&view=rev
Log:
Copied the dep_check.version_comparison() function into the dispersion model
profiling base script.
This will be used to provide compatibility between different relax versions by
allowing the version
numbers to be compared. The function needs to be copied here as older relax
versions do not provide
this function.
