= Local classes and packages =

Templates for some of these classes and packages are in a subdirectory ```templates``` of the ```texmf-local```-directory of your computer. For Linux it is in ```/opt/texmf-local/```. For MacOS it is in ```/usr/local/texlive```.


=== \documentclass{LTHreport} ===
This class is based on [[../LTHthesis|LTHthesis]], but uses A4 paper instead of the smaller E5 paper used by ```LTHthesis```.
By default ```LTHreport``` has section as the highest subdivision. In order to have chapters instead, use the class option ```[chapter]```. The default document type (in the titlepages) is ''Techical Report'', but you may change this.
For other options, [[computerLatexTemplates#LTHreport|see the Template]] and also [[../LTHthesis|LTHthesis]].

=== \documentclass{LTHtwocol} ===
Format for two column documents. The class was originally written for student reports in the project course, FRTN40, but of course it may be used as a basis for any two column document. For options and subcommands, see the template as indicated above.

=== \documentclass{tentamen} ===
Format for exams. You can enter both problems and solutions in the same file, and print each seperatly or individually depending on the options. For additional subcommands, [[computerLatexTemplates#tentamen|see the Template]]
     There is also a collection of [[../BlockDiagram|block diagrams in .eps]] and [[../BlockDiagramsTikZ|block diagrams in TikZ]].
 `[problemsonly]`
   Just prints the problems. This is the form in which exams are to be given.
 `[solutionsonly]`
   Just prints the solutions.


=== \documentclass{brev} ===
Format for letters with the address placed so it fits our window envelopes. For additional commands, see the [[attachment:brev.txt|example]]. [[computerLatexTemplates#brev|Template]]
 `[letterhead]`
    Gives a English language letter header and footer.<<BR>>
 `[brevhuvud]`
    Gives a Swedish language letter header and footer. Also Swedish hyphenation in the letter.

=== \usepackage{problems} ===
A package for a collection of problems and solutions, either for an exam or for a collection of exercises. The class {{{tentamen}}} above uses this package implicitly, so please see its template for further information.
  {{{[chapter]}}} 
    Gives problem numbering by chapter, like 2.4, otherwise it is just a single number.

\BZ     bold math Z
\Ba     bold math a
\Bb     bold math b
