   - &file_delchk_js() and &file_overwritechk_js() routines in structuretags.pm

  if $env{'form.answer_output_mode'} is 'tex' and $env{'form.grade_target'} is 'answer'
  - answers for all resources in page appear after rendering of individual
    resources in .page, when print type is "with answers" for a .page.

- Eliminate some cases where printing would fail.

In process of removing remote control, remote navmap and different icon modes code
- mostly remote navmap related code and files removed

Add/edit/delete composite pages (.page files) via DOCS. Create .sequence and .page files
immediately when folders or pages are added via DOCS (before items have been added to them) - this
allows lonpageflip to work correctly. New help file for Composite Pages. Pages created via
DOCS stored in /uploaded area may contain uploaded files, resources form RES and simple
problems and score upload templates. Other Special documents are not supported.

Modified message when page to be displayed is empty, or contains only hidden items. For the future: modify lonnavmaps so empty pages are not displayed in the map, and modify lonpageflip so empty pages are skipped when jumping to next resource.

More customary LON-CAPA role checking practice.

1. Add lonlocal (line 48) so &mt() call at line 354 is error-free.
2. Changes to sub tracetable().
Most changes are indentation changes to conform to LON-CAPA style.
Functionality changes are: lines 76-79 - detect if resource is hidden, and user has student role. If so lines 82-115 are not executed. Purpose is to display hidden resources in a page to non-students, but to hide them from students. Might cause confusion in the attached discussions, as different students may be commenting on different resources in the page. Recommendation for future is to add an apprpriate note to any feedback window, where feedback is being given on a page with hidden resources.

Pages can be printed now but not for the problems marked as exam ones. There are still LaTeX conflicts between different LaTeX environments. The possibility to print pages was broken down due to use of form hash to pass data to ssi call (earlier it was done trough the ENV hash).

* Bug #1685: anchors on .page, jump there from NAV
* General: NAV did not treat anchors correctly when appending symb

- need to recognize when called with target of meta and gracefully return blank (BUG#2022)

Internationalizing.

Fix bug 1930 - remove target "lonCatInfo" from subm, pgrd & parm from page.

Inline menu on .page resources

Correct filtering of "LON-CAPA Internal" sections.

A lot of things happened here:

* everything menu-related was moved out of lonxml, and into lonmenu
* thus, function calls to registerurl, loadevents and unloadevents modified
* fixed lontex.pm, which actually did not call the right routines
* put in calls to lonmenu::menubuttons, which is supposed to insert buttons
  after the body tag in "textual mode" - this function and registerurl will
  be unified (buttons either in Remote or on top of page)

best wishes to all.

Bugs 818 and 760 are fixed. \strut added to the end of longtable.

Can print pages: 1. with problems;
		 2. with html documents;
                 3. with another pages;
                 4. with mixture if 1.,2., and 3.
Current limitations (working to remove): 1. cannot print a long document or problems;

Fixing bug #675.

Removed what appears to be a perfectly idiotic hack. I truly wish I knew why
it was in there. Hoping this did not break anything else.

- i think the last of bug#574

capable to print pages with multiple columns

See comments for structuretags.pm

Bug 123
Inserts \hline or <hr /> after end of ssi-import depending on course
environment variable pageseparators (shown if "yes").

can print pages, but 1. somebody needs to define the width of minipage
inside the table (corresponds to HTML table) 2. if the table is sufficiently
large somebody has to split the table. Now I am trying to resolve these
problems.

Calls lonsequence for out-of-course-context viewing of maps.
Bug #165

- multiple grading possibilities, go to the menu

now prints pages but still heeds some additional work (mainly cleanup)

Escape the rest of the GET parameters

Escape the URL for feedback

Should be postdata instead of feedurl to emulate Remote

Trying to implement individual eval button - cannot test here.

Minor change for lonxml::registerurl calls.  This should affect nothing!

- was bombing on javascript links

adding in POD documentation; changing void context map statements to
foreach statements; removing references to Apache::lonnet::fileembstyle
and using Apache::loncommon::fileembstyle -Scott Harrison
