X-Git-Tag: mmh-thesis-end~93 X-Git-Url: http://git.marmaro.de/?a=commitdiff_plain;h=90d53cbbe431a89ac2066a527bbfe46ac0f3cbe7;p=mmh mhbuild: Removed support for creating message/external-body parts. Although I really like the concept, I remove the support because I haven't seen any such message in my life. Less code through removing hardly used features is more appealing to me than having support for such nice but hardly used features. The world took a different road than the one MIME proposed. --- diff --git a/man/mhbuild.man1 b/man/mhbuild.man1 index babc1b2..9c68f36 100644 --- a/man/mhbuild.man1 +++ b/man/mhbuild.man1 @@ -114,9 +114,8 @@ than one line, e.g., .fi .RE .PP -There are four kinds of directives: +There are three kinds of directives: \*(lqtype\*(rq, -\*(lqexternal-type\*(rq, \*(lqmessage\*(rq (#forw), and \*(lqbegin\*(rq (#begin). .PP @@ -197,55 +196,7 @@ contents should probably be put in the file specified by the environment variable, instead of directly in your user profile. .PP -.B "(2) The \*(lqexternal-type\*(rq directives -are used to provide a MIME -reference to a content, rather than enclosing the contents itself -(for instance, by specifying an ftp site).
