  24 ;;; Commentary:
  25
  26 ;; `org-lparse' is the entry point for the generic line-oriented
  27 ;; exporter.  `org-do-lparse' is the genericized version of the
  28 ;; original `org-export-as-html' routine.
  29
  30 ;; `org-lparse-native-backends' is a good starting point for
  31 ;; exploring the generic exporter.
  32
  33 ;; Following new interactive commands are provided by this library.
  34 ;; `org-lparse', `org-lparse-and-open', `org-lparse-to-buffer'
  35 ;; `org-replace-region-by', `org-lparse-region'.
  36
  37 ;; Note that the above routines correspond to the following routines
  38 ;; in the html exporter `org-export-as-html',
  39 ;; `org-export-as-html-and-open', `org-export-as-html-to-buffer',
  40 ;; `org-replace-region-by-html' and `org-export-region-as-html'.
  41
  42 ;; The new interactive command `org-lparse-convert' can be used to
  43 ;; convert documents between various formats.  Use this to command,
  44 ;; for example, to convert odt file to doc or pdf format.

2128 ;; Note that org-tables are NOT multi-line and each line is mapped to
2129 ;; a unique row in the exported document.  So if an exported table
2130 ;; needs to contain a single paragraph (with copious text) it needs to
2131 ;; be typed up in a single line. Editing such long lines using the
2132 ;; table editor will be a cumbersome task.  Furthermore inclusion of
2133 ;; multi-paragraph text in a table cell is well-nigh impossible.
2134 ;;
2135 ;; LIST-TABLEs are meant to circumvent the above problems with
2136 ;; org-tables.
2137 ;;
2138 ;; Note that in the example above the list items could be paragraphs
2139 ;; themselves and the list can be arbitrarily deep.
