Commands Overview
-----------------
The git commands can helpfully be split into those that manipulate
-the repository, the cache and the working fileset and those that
-interrogate and compare them.
+the repository, the cache and the working fileset, those that
+interrogate and compare them, and those that moves objects and
+references between repositories.
-There are also some ancilliary programs that can be viewed as useful
+In addition, git itself comes with a spartan set of porcelain
+commands. They are usable but are not meant to compete with real
+Porcelains.
+
+There are also some ancillary programs that can be viewed as useful
aids for using the core commands but which are unlikely to be used by
SCMs layered over git.

--------------------
-Any git comand accepting any <object> can also use the following
+Any git command accepting any <object> can also use the following
symbolic notation:
HEAD::
.git/ The base (overridden with $GIT_DIR)
objects/ The object base (overridden with $GIT_OBJECT_DIRECTORY)
- ??/ 'First 2 chars of object' directories
-
-It can interrogate (but never updates) the following areas:
+ ??/ 'First 2 chars of object' directories.
+ pack/ Packed archives.
refs/ Directories containing symbolic names for objects
(each file contains the hex SHA1 + newline)
heads/ Commits which are heads of various sorts
tags/ Tags, by the tag name (or some local renaming of it)
- snap/ ????
- ... Everything else isn't shared
- HEAD Symlink to refs/heads/<something>
+ */ Any other subdirectory of refs/ can be used to store
+ files similar to what are under refs/heads/.
+ HEAD Symlink to refs/heads/<current-branch-name>
Higher level SCMs may provide and manage additional information in the
GIT_DIR.
'GIT_ALTERNATE_OBJECT_DIRECTORIES'::
Due to the immutable nature of git objects, old objects can be
archived into shared, read-only directories. This variable
- specifies a ":" seperated list of git object directories which
+ specifies a ":" separated list of git object directories which
can be used to search for git objects. New objects will not be
written to these directories.
