gitwhoareyounow
---------------

gitwhoareyounow is used to find a single identity for files that have been
renamed in the history of a project.

E.g., if a file foo.c is created in revision 1 (assuming successive revisions
numbered 1, 2, etc.) and renamed to bar.c in revision 2, gitwhoareyounow
would then return the name bar.c for this file in any revision we consider.

gitwhoareyounow has to be given a repository in which the historical commit
has been checked out, and the name the file had in that commit.

Example:

$ git init
$ date >foo.c
# git add foo.c
# git commit -m "foo.c, rev 1"
$ git mv foo.c bar.c
$ git commit -m "foo.c renamed to bar.c, rev 2"
$ git checkout HEAD~1
$ ls
foo.c
$ gitwhoareyounow . foo.c
bar.c


Multiple files may use the same identity
- - - - - - - - - - - - - - - - - - - - 

E.g., if a file foo.c is created in revision 1, deleted in revision 3, and
then a new file named foo.c is created in revision 4, gitwhoareyounow would
call both of them foo.c


Multiple files sharing the same identity can conflict
- - - - - - - - - - - - - - - - - - - - - - - - - - -

E.g., taking the first example with foo.c renamed to bar.c in revision 3, if
a file bar.c existed in revision 1 but was deleted in revision 2,
gitwhoareyounow running on revision 1 would identify both the foo.c and the
bar.c as bar.c

gitwhoareyounow does not try to resolve such conflicts. This is already
complex enough as it is :-)
