If the target file is on the master, then you can load its entire contents
into a variable via the file() function that David suggested:
$myvar = file('/path/to/file')
If needed, you can then use other Puppet functions to parse out the value
you want.
Alternatively, you can always write a custom function to parse any file
format you want. If the target file is one that you intend to create and
maintain for this purpose, however, then I would recommend using Hiera
instead. It's a little more involved to set up (unless you're on Puppet 3,
where it's built in), but it's the de facto standard for accessing external
data even on Puppet 2.
On the other hand, if your file resides on the node being configured, then
what you're looking for is a custom fact. They are pretty easy to write
and distribute: http://docs.puppetlabs.com/guides/custom_facts.html.
