Stray character in input

[Paul Studdart]

I am running cfengine 2.1.3 for configuring some compute clusters.
Recently I added a second cluster and wanted to use the same
configuration files with an additional section that created different
macros depending on the cluster it was working with. Since each cluster
is in a different domain I decided to test against the domain class set
up by the cfengine program. On my test cluster at home this worked fine
but when I tried it at work it fails with an error message:

 cf.site Syntax error
 Stray character in input (-)

The relevant parts of the cf.site config file are:-

control:
  #==============
  # Home cluster
  #==============
  lac_ddd_co_uk::
    macros .......

  #=========================
  # Work Scooby Cluster
  #=========================
  scooby_ddd-dd_xxx_uk::
    macros ........

So it looks like it's the - character in the domain name that is the
cause of the problem. Since I cannot change the domain name assigned to
the organisation is there any way of escaping the - character in this
instance. I could create a mythical top level domain on the clusters
name servers but I would prefer another solution.

Any help, suggestions would be very gratefully received.
