Revision 1.3: download - view: text, annotated - select for diffs
Mon Jul 6 17:12:47 2009 UTC (14 years, 10 months ago) by bisitz
Branches: MAIN
CVS tags: version_2_9_99_0, bz6209-base, bz6209, bz2851, PRINT_INCOMPLETE_base, PRINT_INCOMPLETE, HEAD, GCI_3

Consistent problem templates:
- New line after each tag (not for texts in foils)
- One empty row after each end tag and before new start tag for second level tags
- No indentation for second level tags, e.g. <script>
- Four white spaces as indentation for each further sub level
    Exceptions:
        -Content (mostly text) in separate line(s): no indentation
        - Concept groups: same indentation as foilgroup
          (allows to insert code from problems without concept groups without changing the indentation and vice versa)
- No new line at end of template
- Removed new lines from within the middle of default texts
- Added one blank each after "<m>$" and before "$</m>" to ensure no misinterpretation neither by human nor by machine (e.g. "<m>$x" is not "<m>$ $x")
- Replaced deprecated font tag in <instructorcomment> by CSS
- Removed dos line endings
- dos2unix conversion
