SYNOPSIS
--------
-'git-commit-tree' <tree> [-p <parent commit>]\ < changelog
+'git commit-tree' <tree> [-p <parent commit>]\* < changelog
DESCRIPTION
-----------
+This is usually not what an end user wants to run directly. See
+linkgit:git-commit[1] instead.
+
Creates a new commit object based on the provided tree object and
-emits the new commit object id on stdout. If no parent is given then
-it is considered to be an initial tree.
+emits the new commit object id on stdout.
-A commit object usually has 1 parent (a commit after a change) or up
-to 16 parents. More than one parent represents a merge of branches
-that led to them.
+A commit object may have any number of parents. With exactly one
+parent, it is an ordinary commit. Having more than one parent makes
+the commit a merge between several lines of history. Initial (root)
+commits have no parents.
While a tree represents a particular directory state of a working
directory, a commit represents that state in "time", and explains how
Normally a commit would identify a new "HEAD" state, and while git
doesn't care where you save the note about that state, in practice we
-tend to just write the result to the file `.git/HEAD`, so that we can
-always see what the last committed state was.
+tend to just write the result to the file that is pointed at by
+`.git/HEAD`, so that we can always see what the last committed
+state was.

Commit Information
------------------
- author name, email and date
- committer name and email and the commit time.
-If not provided, "git-commit-tree" uses your name, hostname and domain to
-provide author and committer info. This can be overridden using the
-following environment variables.
+While parent object ids are provided on the command line, author and
+committer information is taken from the following environment variables,
+if set:
GIT_AUTHOR_NAME
GIT_AUTHOR_EMAIL
GIT_AUTHOR_DATE
GIT_COMMITTER_NAME
GIT_COMMITTER_EMAIL
+ GIT_COMMITTER_DATE
+ EMAIL
(nb "<", ">" and "\n"s are stripped)
-A commit comment is read from stdin (max 999 chars). If a changelog
-entry is not provided via "<" redirection, "git-commit-tree" will just wait
+In case (some of) these environment variables are not set, the information
+is taken from the configuration items user.name and user.email, or, if not
+present, system user name and fully qualified hostname.

+A commit comment is read from stdin. If a changelog
+entry is not provided via "<" redirection, 'git-commit-tree' will just wait
for one to be entered and terminated with ^D.
