How do I set variable if a specific package version is installed in CFEngine

Question

A script needs to support two servers, Fedora and Centos, with different versions of httpd (Apache). CFEngine is used to create the configuration file and it needs to put different sections to the file depending on which httpd version is installed in the system. How can I set a variable to true/false depending on which version is installed so that I can then generate the file appropriately?

All the examples I could find only deal with installing, upgrading or removing packages.

Can anyone help me with this?

Thanks.

Here is what you can do.Just use packagesmatching to get the version of httpd that's currently installed. You might combine it with ifelse, strcmp, regcmp so that you can set different variables and classes which you might use in your template.

I hope the above information will be helpful for you.
