Usage: ./${SCRIPT} [-h] [-d] shownumber
|
|
|
|
Version: $VERSION
|
|
|
|
Runs Pandoc against assets for a particular show, catering for the case when
|
|
a host sends in external notes (referenced from the main notes) in Markdown
|
|
format rather than HTML.
|
|
|
|
For the moment the only format catered for is Markdown, in files with the
|
|
suffix 'md' or 'mkd'
|
|
|
|
Options:
|
|
-h Print this help
|
|
-d Select dry run mode
|
|
|
|
Arguments:
|
|
shownumber
|
|
|
|
Examples
|
|
./${SCRIPT} -h
|
|
./${SCRIPT} -d 2240
|
|
