Tags in Mercurial
hg tag
Note: If you are migrating from ["CVS"], please [:CvsConcepts#tag:read this discussion of CVS tags] before you continue.
A tag is a symbolic identifier for a ["ChangeSet"]. It can contain any characters except ":" (colon), "\r" (Carriage Return) or "\n" (Line Feed).
["Mercurial"] has two kinds of tag.
A local tag is a convenience identifier that is not revision controlled, does not propagate with other changes, and lives in the .hg/localtags file in a repository.
A "regular" tag (with no special specifier) is revision controlled, does propagate with other changes, and lives in the .hgtags file in a repository. (It is therefore possible to remove tags by editing .hgtags and committing the change - this being the nearest equivalent to cvs tag -d).
