.B status
.UNINDENT

.sp
where n is a single character representing notmuch database status
.INDENT 0.0
.INDENT 3.5
.INDENT 0.0
.TP
.B A
.UNINDENT
.sp

pull, but not restored to notmuch database).
.INDENT 0.0

run to update this.
.INDENT 0.0

.UNINDENT
.UNINDENT
.SH REPOSITORY CONTENTS
.sp
The tags are stored in the git repo (and exported) as a set of empty
files. These empty files are contained within a directory named after
the message\-id.
.sp
In what follows \fIencode()\fP represents a POSIX filesystem safe
encoding. The encoding preserves alphanumerics, and the characters
\fI+\-_@=.,:\fP\&.  All other octets are replaced with \fI%\fP followed by a two
digit hex number.
.sp
Currently \fI\%notmuch\-git\fP can read any format version, but can only
create (via \fI\%init\fP) \fI\%version 1\fP repositories.
.SS Version 0
.sp
This is the legacy format created by the \fInmbug\fP tool prior to release
0.37.  For a message with Message\-Id \fIid\fP, for each tag \fItag\fP, there
is an empty file with path
.INDENT 0.0
.INDENT 3.5
tags/ \fIencode\fP (\fIid\fP) / \fIencode\fP (\fItag\fP)
.UNINDENT
.UNINDENT
.SS Version 1
.sp
In format version 1 and later, the format version is contained in a
top level file called FORMAT.
.sp
For a message with Message\-Id \fIid\fP, for each tag \fItag\fP, there
is an empty file with path
.INDENT 0.0
.INDENT 3.5
tags/ \fIhash1\fP (\fIid\fP) / \fIhash2\fP (\fIid\fP) \fIencode\fP (\fIid\fP) / \fIencode\fP (\fItag\fP)
.UNINDENT
.UNINDENT
.sp
The hash functions each represent one byte of the \fIblake2b\fP hex
digest.
.sp
Compared to \fI\%version 0\fP, this reduces the
number of subdirectories within each directory.
.SH REPOSITORY LOCATION
.sp
\fI\%notmuch\-git\fP uses the first of the following with a non\-empty
value to locate the git repository.
.INDENT 0.0
