.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Modify a configuration file with the values passed on the command line.
These command must follow the syntax defined in Config::Model::Loader
(which is similar to the output of cme dump command)
.PP
Example:
.PP
.Vb 2
\&   cme modify dpkg source format="(3.0) quilt"
\&   cme modify multistrap my_mstrap.conf sections:base source="http://ftp.fr.debian.org"
.Ve
.PP
Some application like dpkg-copyright allows you to override the
configuration file name. The problem is to make the difference between
the overridden file name and the modification instruction you want to
apply.
.PP
Either you specify both overridden file name modifications:
.PP
.Vb 1
\&   cme modify dpkg\-copyright ubuntu/copyright \*(AqComment="Silly example"
.Ve
.PP
Or you use \f(CW\*(C`~~\*(C'\fR to use the default file name:
.PP
.Vb 1
\&   cme modify dpkg\-copyright ~~ \*(AqComment="Another silly example"
.Ve
.PP
Another example which restores the default value of the text of all \s-1GPL\s0 like licenses :
.PP
.Vb 1
\&   cme modify dpkg\-copyright ~~ \*(AqLicense=~/GPL/ text~\*(Aq
.Ve
.PP
Or update the copyright years of the package maintainer's file:
.PP
.Vb 1
\&   cme modify dpkg\-copyright ~~ \*(AqFile=debian/* Copyright=~s/2013/2014/\*(Aq

Force a save even if no change was done. Useful to reformat the configuration file.
