+SYNOPSIS

+-----------
+Annotates each line in the given file with information from the commit
+which introduced the line. Optionally annotates from a given revision.

+they use slightly different output formats, and this command exists only
+for backward compatibility to support existing scripts, and provide a more
+familiar command name for people coming from other SCM systems.
