| 74 | % \section{User guide} |
| 75 | % |
| 76 | % Not a lot to say, really. It's a document class for sets of slides and |
| 77 | % their notes. I've based it on Timothy van Zandt's \package{seminar} class, |
| 78 | % but there are some important tweaks and bug fixes. |
| 79 | % |
| 80 | % \DescribeMacro\topic |
| 81 | % The most important new feature is that the sectioning commands create |
| 82 | % little summary pages automatically. Each |\section| is given a summary |
| 83 | % page. The subsections are listed one per line, with the topics covered in |
| 84 | % that subsection. A topic is introduced by saying |
| 85 | % \syntax{"\\topic{"<text>"}"}. This only has an effect in slides-only mode; |
| 86 | % it's ignored when typesetting notes. |
| 87 | % |
| 88 | % \DescribeMacro\xcalways |
| 89 | % The notes come out best if you put the sectioning commands outside of the |
| 90 | % slides. However, in order for a slides-only run to actually notice them, |
| 91 | % you need to mark them as `interesting'. You can write |
| 92 | % \begin{quote} |
| 93 | % \syntax{"\\xcalways"<anything>"\\x"} |
| 94 | % \end{quote} |
| 95 | % to have \synt{anything} recognized even in slides-only mode. |
| 96 | % |
| 97 | % \DescribeMacro\head |
| 98 | % The heading at the top of a slide is typeset by saying |
| 99 | % \syntax{"\\head{"<text>"}"}. Headings come out in a large sans face by |
| 100 | % default. Feel free to redefine the command if you don't like that. |
| 101 | % |
| 102 | % \DescribeMacro\resetseq |
| 103 | % \DescribeMacro\seq |
| 104 | % Maybe it's a deficiency on my part, but I tend to end up with several |
| 105 | % slides on the same subject, and rather than think of different headings I |
| 106 | % tend to number the successive slides. Say |\resetseq| before the heading |
| 107 | % of the first in a series and insert the number by saying |\seq|. Should it |
| 108 | % be necessary, you can label and make cross-references to |\seq|uence |
| 109 | % numbers. |
