Tag handling (Semantic Manual)

A tag represents an individual item found in a buffer, such as a function or variable. Tag handling is handled in several source files.

semantic/tag.el: Basic tag creation, queries, cloning, binding, and unbinding.
semantic/tag-write.el: Write a tag or tag list to a stream. These routines are used by semanticdb-file.el when saving a list of tags.
semantic/tag-file.el: Files associated with tags. Goto-tag, file for include, and file for a prototype.
semantic/tag-ls.el: Language dependent features of a tag, such as parent calculation, slot protection, and other states like abstract, virtual, static, and leaf.
semantic/dep.el: Include file handling. Contains the include path concepts, and routines for looking up file names in the include path.
semantic/format.el: Convert a tag into a nicely formatted and colored string. Use semantic-test-all-format-tag-functions to test different output options.
semantic/find.el: Find tags matching different conditions in a tag table. These routines are used by semanticdb-find.el once the database has been converted into a simpler tag table.
semantic/sort.el: Sorting lists of tags in different ways. Includes sorting a plain list of tags forward or backward. Includes binning tags based on attributes (bucketize), and tag adoption for multiple references to the same thing.
semantic/doc.el: Capture documentation comments from near a tag.
