-\sec References
-
-There is a numbered equation.
-The number is auto-generated by `\eqmark` sequence.
-$$\label[my-eq]
- a^2 + b^2 = c^2 \eqmark
-$$
-We can refer to Equation~\ref[my-eq]
-on page~\pgref[my-eq].
-We can refer to Table~\ref[my-tab] in
-Section~\ref[tab-sec] too. And Figure~\ref[my-pic]
-is on page~\pgref[my-pic].
-
-\sec Hyperlinks
-
-You can refer to \url{http://petr.olsak.net} using `\url`.
-Or use `\ulink` if the raw URL needs to be hidden:
-\ulink[http://petr.olsak.net/optex]{\OpTeX/ page}.
-The parameter text is colorized and it becomes
-an active link if the `\hyperlinks` sequence
-is used at the beginning of the document.
-Internal links are activated too.
-
-\sec[tab-sec] Tables
-
-The `\table` sequence can be used
-instead of \"low level" `\halign`.
-The following table is framed by `\frame` sequence
-in order to get a double frame.

-\sec Images
-
-The images (PDF, JPG, PNG, TIFF) can be inserted
-by `\inspic` sequence. The `\caption`

-In-text verbatim is surrounded by the character declared
-by `\activettchar` sequence. The listing can be surrounded
-by `\begtt` and `\endtt` sequences
-\begtt
-This is verbatim.
- All characters are printed $$, \, # etc.
-\endtt
-or it can be included by `\verbinput` from external file.

-\sec Math
-
-The Math alphabets
-`\mit`, `\cal`, `\script`, `\frak`, `\bbchar`, `\bi`
-are provided. For example:
-$$
- {\bi A} = \pmatrix {\cal C & \script C \cr
- \frak M & \bbchar R }.
-$$
-Hundreds of AMS symbols are available:
-$\sphericalangle, \boxplus, \Cup, \Cap, \ldots$
-
-\sec Others
-
-The `\fontfam` command selects a desired family of fonts.
-The `\typosize` or `\typoscale` sequences set the size
-and baselineskip of used fonts (including math fonts).
-The `\fnote` generates a footnote\fnote{Like this} and
-`\mnote` generates a margin note.
-The `\margins` sets margins and paper dimensions.
-The `\cite` sequence can be used for bibliographic citations.
-The `\bib` sequence creates one bibliography record. Or
-you can use `\usebib` for direct access to the {\tt.bib} files.
-The list of features does not end here\dots
