;;
;; Highlight any include that is in a state the user may care about.
;; The basic idea is to have the state be highly visible so users will
;; as 'what is this?" and get the info they need to fix problems that
;; are otherwise transparent when trying to get smart completion
;; working.

This means that Semantic has not been able to locate this file on disk.

that file to provide coding assistance.

If this is a system header and you want it excluded from Semantic's
searches (which may be desirable for speed reasons) then you can
safely ignore this state.

If this is a system header, and you want to include it in Semantic's
searches, then you will need to use:

If this is an include file that belongs to your project, then you may

to manage your project.  See the ede manual for projects that will
wrap existing project code for Semantic's benefit.

This means that Semantic has located this header file on disk

This can take a while in large projects.

Alternately, you can call:

M-x semanticdb-find-test-translate-path RET

to search path Semantic uses to perform completion.


If you think this header tag is marked in error, you may need to do:

C-u M-x bovinate RET

to refresh the tags in this buffer, and recalculate the state.
If you find a repeatable case where a header is marked in error,
report it to cedet-devel@lists.sf.net.") )))
