-/**
- * e_text_to_html:
- * @input: a NUL-terminated input buffer
- * @flags: some combination of the E_TEXT_TO_HTML_* flags defined
- * in e-html-utils.h
- *
- * This takes a buffer of text as input and produces a buffer of
- * "equivalent" HTML, subject to certain transformation rules.
- *
- * The set of possible flags is:
- *
- *   - E_TEXT_TO_HTML_PRE: wrap the output HTML in <PRE> and </PRE>.
- *     Should only be used if @input is the entire buffer to be
- *     converted. If e_text_to_html is being called with small pieces
- *     of data, you should wrap the entire result in <PRE> yourself.
- *
- *   - E_TEXT_TO_HTML_CONVERT_NL: convert "\n" to "<BR>\n" on output.
- *     (should not be used with E_TEXT_TO_HTML_PRE, since that would
- *     result in double-newlines).
- *
- *   - E_TEXT_TO_HTML_CONVERT_SPACES: convert a block of N spaces
- *     into N-1 non-breaking spaces and one normal space. A space
- *     at the start of the buffer is always converted to a
- *     non-breaking space, regardless of the following character,
- *     which probably means you don't want to use this flag on
- *     pieces of data that aren't delimited by at least line breaks.
- *
- *   - E_TEXT_TO_HTML_CONVERT_URLS: wrap <a href="..."> </a> around
- *     strings that look like URLs.
