[O] Batch export to html

[Vikas Rawal]

I would like to export an org file to html using a batch command. This
is the command I tried.

emacs --batch --load=$HOME/lisp/org-7.01/lisp/org.el --eval "(setq
org-export-headline-levels 1)" --visit=$HOME/file.org --funcall 
org-export-as-html-batch

But I get an error which says: 

Symbol's function definition is void: org-in-block-p

Could anyone explain what this could mean?

Thanks,

Vikas
