Subject: nmbug: move from contrib to devel
X-Git-Tag: 0.16_rc1~214
X-Git-Url: https://git.notmuchmail.org/git?p=notmuch;a=commitdiff_plain;h=41a29a84721235e33aff23bf6ef61b9ffdded2ef

nmbug: move from contrib to devel

There seems to be consensus to use presence in contrib as
documentation of limited support by the notmuch developers; in fact
nmbug is pretty integrated into our current development process, so
devel seems more appropriate.

-=head1 NAME
-
-nmbug - manage notmuch tags about notmuch
-
-=head1 SYNOPSIS
-
-nmbug subcommand [options]
-
-B<nmbug help> for more help
-
-=head1 OPTIONS
-
-=head2 Most common commands
-
-=over 8
-
-=item B<commit> [message]
-
-Commit appropriately prefixed tags from the notmuch database to
-git. Any extra arguments are used (one per line) as a commit message.
-
-=item  B<push> [remote]
-
-push local nmbug git state to remote repo
-
-=item  B<pull> [remote]
-
-pull (merge) remote repo changes to notmuch. B<pull> is equivalent to
-B<fetch> followed by B<merge>.
-
-=back
-
-=head2 Other Useful Commands
-
-=over 8
-
-=item B<checkout>
-
-Update the notmuch database from git. This is mainly useful to discard
-your changes in notmuch relative to git.
-
-=item B<fetch> [remote]
-
-Fetch changes from the remote repo (see merge to bring those changes
-into notmuch).
-
-=item B<help> [subcommand]
-
-print help [for subcommand]
-
-=item B<log> [parameters]
-
-A simple wrapper for git log. After running C<nmbug fetch>, you can
-inspect the changes with C<nmbug log HEAD..FETCH_HEAD>
-
-=item B<merge>
-
-Merge changes from FETCH_HEAD into HEAD, and load the result into
-notmuch.
-
-=item  B<status>
-
-Show pending updates in notmuch or git repo. See below for more
-information about the output format.
-
-=back
-
-=head2 Less common commands
-
-=over 8
-
-=item B<archive>
-
-Dump a tar archive (using git archive) of the current nmbug tag set.
-
-=back
-
-=head1 STATUS FORMAT
-
-B<nmbug status> prints lines of the form
-
-   ng Message-Id tag
-
-where n is a single character representing notmuch database status
-
-=over 8
-
-=item B<A>
-
-Tag is present in notmuch database, but not committed to nmbug
-(equivalently, tag has been deleted in nmbug repo, e.g. by a pull, but
-not restored to notmuch database).
-
-=item B<D>
-
-Tag is present in nmbug repo, but not restored to notmuch database
-(equivalently, tag has been deleted in notmuch)
-
-=item B<U>
-
-Message is unknown (missing from local notmuch database)
-
-=back
-
-The second character (if present) represents a difference between remote
-git and local. Typically C<nmbug fetch> needs to be run to update this.
-
-=over 8
-
-
-=item B<a>
-
-Tag is present in remote, but not in local git.
-
-
-=item B<d>
-
-Tag is present in local git, but not in remote git.
-
-
-=back
-
-=head1 DUMP FORMAT
-
-Each tag $tag for message with Message-Id $id is written to
-an empty file
-
-	tags/encode($id)/encode($tag)
-
-The encoding preserves alphanumerics, and the characters "+-_@=.:,"
-(not the quotes).  All other octets are replaced with '%' followed by
-a two digit hex number.
-
-=head1 ENVIRONMENT
-
-B<NMBGIT> specifies the location of the git repository used by nmbug.
-If not specified $HOME/.nmbug is used.
-
-B<NMBPREFIX> specifies the prefix in the notmuch database for tags of
-interest to nmbug. If not specified 'notmuch::' is used.

+
+=head1 SYNOPSIS

+nmbug subcommand [options]
+
+B<nmbug help> for more help
+
+=head1 OPTIONS
+
+=head2 Most common commands
+
+=over 8
+
+=item B<commit> [message]
+
+Commit appropriately prefixed tags from the notmuch database to
+git. Any extra arguments are used (one per line) as a commit message.
+
+=item  B<push> [remote]
+
+push local nmbug git state to remote repo
+
+=item  B<pull> [remote]
+
+pull (merge) remote repo changes to notmuch. B<pull> is equivalent to
+B<fetch> followed by B<merge>.
+
+=back
+
+=head2 Other Useful Commands
+
+=over 8
+
+=item B<checkout>
+
+Update the notmuch database from git. This is mainly useful to discard
+your changes in notmuch relative to git.
+
+=item B<fetch> [remote]
+
+Fetch changes from the remote repo (see merge to bring those changes
+into notmuch).
+
+=item B<help> [subcommand]
+
+print help [for subcommand]
+
+=item B<log> [parameters]
+
+A simple wrapper for git log. After running C<nmbug fetch>, you can
+inspect the changes with C<nmbug log HEAD..FETCH_HEAD>
+
+=item B<merge>
+
+Merge changes from FETCH_HEAD into HEAD, and load the result into
+notmuch.
+
+=item  B<status>
+
+Show pending updates in notmuch or git repo. See below for more
+information about the output format.

+
+=over 8
+
+=item B<archive>
+
+Dump a tar archive (using git archive) of the current nmbug tag set.
+
+=back
+
+=head1 STATUS FORMAT
+
+B<nmbug status> prints lines of the form
+
+   ng Message-Id tag
+
+where n is a single character representing notmuch database status
+
+=over 8
+
+=item B<A>
+
+Tag is present in notmuch database, but not committed to nmbug
+(equivalently, tag has been deleted in nmbug repo, e.g. by a pull, but
+not restored to notmuch database).
+
+=item B<D>
+
+Tag is present in nmbug repo, but not restored to notmuch database
+(equivalently, tag has been deleted in notmuch)
+
+=item B<U>
+
+Message is unknown (missing from local notmuch database)
+
+=back
+
+The second character (if present) represents a difference between remote
+git and local. Typically C<nmbug fetch> needs to be run to update this.
+
+=over 8
+
+
+=item B<a>
+
+Tag is present in remote, but not in local git.
+
+
+=item B<d>
+
+Tag is present in local git, but not in remote git.
+
+
+=back
+
+=head1 DUMP FORMAT
+
+Each tag $tag for message with Message-Id $id is written to
+an empty file
+
+	tags/encode($id)/encode($tag)
+
+The encoding preserves alphanumerics, and the characters "+-_@=.:,"
+(not the quotes).  All other octets are replaced with '%' followed by
+a two digit hex number.
+
+=head1 ENVIRONMENT
+
+B<NMBGIT> specifies the location of the git repository used by nmbug.
+If not specified $HOME/.nmbug is used.
+
+B<NMBPREFIX> specifies the prefix in the notmuch database for tags of
+interest to nmbug. If not specified 'notmuch::' is used.
