 I would like to find out the value of the "basedir" entry in the MDB for
 the current machine.  I currently have to do:

 {{{
 simdir=$(sim print-mdb-entry datura|grep '^[ \t]*basedir[ \t]*=[
 \t]\(.*\)[\t ]*$'|awk '{print $3}')
 }}}

 This is quite ugly, and also requires me to know that the current machine
 is "datura".  I would like to be able to do

 {{{
 sim print-mdb-entry basedir
 }}}

 and have it print the value of basedir for the current machine.  If I
 instead specify a different machine,

 {{{
 sim --machine ranger print-mdb-entry basedir
 }}}

 then it could print the value for the other machine.  This would be much
 more intuitive and useful than the current behaviour.
