generated because a ref change was pushed to the repository containing
the project "theslinux-home".

    git.hook.post-receive-email.sh: - $describe from commit subject
    
    For some reason, the tag do not reflect exactly what is going on. E.g,
    the :home repository has no tag, and tag is only useful for minor issue.
    While :system repository has many kind of tags.
    
    TOD: We should take a look at the use of $describe later

    git.hook.post-receive-email.sh: apply a Debian patch
    
    From d41b94fca5748b0e51f7d505641c396328714813 Mon Sep 17 00:00:00 2001

    Subject: [PATCH 02/12] post-receive-email: defend against non-utf8
     i18n.logoutputencoding setting
    
    The post-receive-email example hook includes a description of the
    repository taken from $GIT_DIR/description in the emails it sends.
    Gitweb also uses that file and assumes it to be UTF-8. When
    [i18n] logoutputencoding is not UTF-8, the result is a message
    composed with multiple encodings.
    
    This patch teaches post-receive-email to use plumbing where possible
    and to explicitly declare what encoding it expects output to use so
    the output uses UTF-8 consistently.
    
    Making the email charset configurable is left as an exercise for the
    interested reader.

    git.hook.post-receive-email.sh: apply a Debian patch
    
    From 1ff228ad3d4df35beba00cbffcf299a463f8f9bf Mon Sep 17 00:00:00 2001
    From: Gerrit Pape <pape@xxxxxxxxxxx>
    Date: Thu, 11 Dec 2008 20:27:21 +0000
    Subject: [PATCH 01/12] hooks/post-receive-email: set encoding to utf-8
    
    Some email clients (e.g., claws-mail) display the message body
    incorrectly when the charset is not defined explicitly in a
    Content-Type header.  "git log" generates logs in UTF-8 encoding by
    default, so add a Content-Type header declaring that encoding to
    the emails the post-receive-email example hook sends.
    
    [jn: also setting the Content-Transfer-Encoding so MTAs know what
     kind of mangling might be needed when sending to a non 8-bit clean
     SMTP host]

+# Copyright (c) 2007 Andy Parkins
+#
+# An example hook script to mail out commit update information.  This hook
+# sends emails listing new revisions to the repository introduced by the
+# change being reported.  The rule is that (for branch updates) each commit
+# will appear on one email and one email only.
+#
+# This hook is stored in the contrib/hooks directory.  Your distribution
+# will have put this somewhere standard.  You should make this script
+# executable then link to it in the repository you would like to use it in.
+# For example, on debian the hook is stored in
+# /usr/share/git-core/contrib/hooks/post-receive-email:
+#
+#  chmod a+x post-receive-email
+#  cd /path/to/your/repository.git
+#  ln -sf /usr/share/git-core/contrib/hooks/post-receive-email 
hooks/post-receive
+#
+# This hook script assumes it is enabled on the central repository of a
+# project, with all users pushing only to it and not between each other.  It
+# will still work if you don't operate in that style, but it would become
+# possible for the email to be from someone other than the person doing the
+# push.
+#
+# To help with debugging and use on pre-v1.5.1 git servers, this script will
+# also obey the interface of hooks/update, taking its arguments on the
+# command line.  Unfortunately, hooks/update is called once for each ref.
+# To avoid firing one email per ref, this script just prints its output to
+# the screen when used in this mode.  The output can then be redirected if
+# wanted.
+#
+# Config
+# ------
+# hooks.mailinglist
+#   This is the list that all pushes will go to; leave it blank to not send
+#   emails for every ref update.
+# hooks.announcelist
+#   This is the list that all pushes of annotated tags will go to.  Leave it
+#   blank to default to the mailinglist field.  The announce emails lists
+#   the short log summary of the changes since the last annotated tag.
+# hooks.envelopesender
+#   If set then the -f option is passed to sendmail to allow the envelope
+#   sender address to be set
+# hooks.emailprefix
+#   All emails have their subjects prefixed with this prefix, or "[SCM]"
+#   if emailprefix is unset, to aid filtering
+# hooks.showrev
+#   The shell command used to format each revision in the email, with
+#   "%s" replaced with the commit id.  Defaults to "git rev-list -1
+#   --pretty %s", displaying the commit id, author, date and log
+#   message.  To list full patches separated by a blank line, you
+#   could set this to "git show -C %s; echo".
+#   To list a gitweb/cgit URL *and* a full patch for each change set, use this:
+#     "t=%s; printf 'http://.../?id=%%s' \$t; echo;echo; git show -C \$t; echo"
+#   Be careful if "..." contains things that will be expanded by shell "eval"
+#   or printf.
+# hooks.emailmaxlines
+#   The maximum number of lines that should be included in the generated
+#   email body. If not specified, there is no limit.
+#   Lines beyond the limit are suppressed and counted, and a final
+#   line is added indicating the number of suppressed lines.
+# hooks.diffopts
+#   Alternate options for the git diff-tree invocation that shows changes.
+#   Default is "--stat --summary --find-copies-harder". Add -p to those
+#   options to include a unified diff of changes in addition to the usual
+#   summary output.
+#
+# Notes
+# -----
+# All emails include the headers "X-Git-Refname", "X-Git-Oldrev",
+# "X-Git-Newrev", and "X-Git-Reftype" to enable fine tuned filtering and
+# give information for debugging.

+       # N is $newrev for $refname
+       # X is a revision pointed to by some other ref, for which we may

+       # In this case we want to issue an email containing only revisions
+       # 3, 4, and N.  Given (almost) by
+       #
+       #  git rev-list N ^O --not --all
+       #
+       # The reason for the "almost", is that the "--not --all" will take
+       # precedence over the "N", and effectively will translate to
+       #
+       #  git rev-list N ^O ^X ^N
+       #
+       # So, we need to build up the list more carefully.  git rev-parse
+       # will generate a list of revs that may be fed into git rev-list.
+       # We can get it to make the "--not --all" part and then filter out
+       # the "^N" with:
+       #
+       #  git rev-parse --not --all | grep -v N
+       #
+       # Then, using the --stdin switch to git rev-list we have effectively
+       # manufactured
+       #
+       #  git rev-list N ^O ^X
+       #
+       # This leaves a problem when someone else updates the repository
+       # while this script is running.  Their new value of the ref we're
+       # working on would be included in the "--not --all" output; and as
+       # our $newrev would be an ancestor of that commit, it would exclude
+       # all of our commits.  What we really want is to exclude the current
+       # value of $refname from the --not list, rather than N itself.  So:
+       #
+       #  git rev-parse --not --all | grep -v $(git rev-parse $refname)
+       #
+       # Get's us to something pretty safe (apart from the small time
+       # between refname being read, and git rev-parse running - for that,
+       # I give up)
+       #
+       #
+       # Next problem, consider this:
+       #   * --- B --- * --- O ($oldrev)
+       #          \
+       #           * --- X --- * --- N ($newrev)
+       #
+       # That is to say, there is no guarantee that oldrev is a strict
+       # subset of newrev (it would have required a --force, but that's
+       # allowed).  So, we can't simply say rev-list $oldrev..$newrev.
+       # Instead we find the common base of the two revs and list from
+       # there.
+       #
+       # As above, we need to take into account the presence of X; if
+       # another branch is already in the repository and points at some of
+       # the revisions that we are about to output - we don't want them.
+       # The solution is as before: git rev-parse output filtered.
+       #
+       # Finally, tags: 1 --- 2 --- O --- T --- 3 --- 4 --- N
+       #
+       # Tags pushed into the repository generate nice shortlog emails that
+       # summarise the commits between them and the previous tag.  However,
+       # those emails don't include the full commit messages that we output
+       # for a branch update.  Therefore we still want to output revisions
+       # that have been output on a tag email.
+       #
+       # Luckily, git rev-parse includes just the tool.  Instead of using
+       # "--all" we use "--branches"; this has the added benefit that
+       # "remotes/" will be ignored as well.
+
+       # List all of the revisions that were removed by this update, in a
