[Xebar Saram]

Hi list

i manage to export using the publish function for html. i really want actually to publih to txt and found these function in the mailing list:

org-publish-org-to-ascii
org-publish-org-to-latin1
org-publish-org-to-utf8

i have tried using them instead of html but got this error:

funcall: Symbol's function definition is void: org-publish-org-to-ascii

any ideas anyone?
