2582 Check if a function by name
2583 \"org-<backend>-format-source-code-or-example\" is bound.  If yes,
2584 use it as the custom formatter.  Otherwise, use the default
2585 formatter.  Default formatters are provided for docbook, html,
2586 latex and ascii backends.  For example, use
2587 `org-html-format-source-code-or-example' to provide a custom
2588 formatter for export to \"html\".

2590 If LANG is nil, do not add any fontification.
2591 OPTS contains formatting options, like `-n' for triggering numbering lines,
2592 and `+n' for continuing previous numbering.
2593 Code formatting according to language currently only works for HTML.
2594 Numbering lines works for all three major backends (html, latex, and ascii).

2801 SKIP1 and SKIP2 are the number of lines that are to be skipped at
2802 the beginning and end of TEXT.  Use these to skip over
2803 backend-specific lines pre-pended or appended to the original
2804 source block.
2805
2806 NUMBER is non-nil if the literal example specifies \"+n\" or
2807 \"-n\" switch.  If NUMBER is non-nil add line numbers.
2808
2809 CONT is non-nil if the literal example specifies \"+n\" switch.
2810 If CONT is nil, start numbering this block from 1.  Otherwise
2811 continue numbering from the last numbered block.
2812
2813 REPLACE-LABELS is dual-purpose.
2814 1. It controls the retention of labels in the exported block.
2815 2. It specifies in what manner the links (or references) to a
2816    labeled line be formatted.
2817
2818 REPLACE-LABELS is the symbol `keep' if the literal example
2819 specifies \"-k\" option, is numeric if the literal example
2820 specifies \"-r\" option and is nil otherwise.
2821
2822 Handle REPLACE-LABELS as below:
2823 - If nil, retain labels in the exported block and use
2824   user-provided labels for referencing the labeled lines.
2825 - If it is a number, remove labels in the exported block and use
2826   one of line numbers or labels for referencing labeled lines based
2827   on NUMBER option.
2828 - If it is a keep, retain labels in the exported block and use
2829   one of line numbers or labels for referencing labeled lines
2830   based on NUMBER option.
2831
2832 LABEL-FORMAT is the value of \"-l\" switch associated with
2833 literal example.  See `org-coderef-label-format'.
2834
2835 PREPROCESS is intended for backend-agnostic handling of source
2836 block numbering.  When non-nil do the following:
2837 - do not number the lines
2838 - always strip the labels from exported block
2839 - do not make the labeled line a target of an incoming link.
2840   Instead mark the labeled line with `org-coderef' property and
2841   store the label in it."
