Hello,

I need to generate a workplan (GANTT chart) and taskjuggler would seem
to be the best way forward given that there is some support for it in
org.  However, I am having a little problem with it, primarily due to
my likely lack of understanding of how custom variables and file local
variables interact.

Specifically, org-taskjuggler.el defines a customisable variable,
org-export-taskjuggler-default-project-duration.  I don't necessarily
want to change the default overall but I do want to have a file
specific value.  I have tried using -*- to define the value of this
variable in the file.  This value is taken into account correctly,
according to emacs:

,----
| org-export-taskjuggler-default-project-duration is a variable defined in `org-taskjuggler.el'.
| Its value is 1300
| Local in buffer workplan.org; global value is 280
| 
|   This variable is a file local variable.
`----

However, org-taskjuggler seems to use the global value regardless.  Is
there something I need to do to get it to pay attention to my file
local variable value?  A pointer to a relevant section in the emacs
lisp manual would suffice as it's about time I learned a bit about
this!

Thanks,
eric
