Relative items adjust a date (or the current date if none) forward or backward. The effects of relative items accumulate. Here are some examples:
1 year
1 year ago
3 years
2 days
The unit of time displacement may be selected by the string `year' or `month' for moving by whole years or months. These are fuzzy units, as years and months are not all of equal duration. More precise units are `fortnight' which is worth 14 days, `week' worth 7 days, `day' worth 24 hours, `hour' worth 60 minutes, `minute' or `min' worth 60 seconds, and `second' or `sec' worth one second. An `s' suffix on these units is accepted and ignored.
The unit of time may be preceded by a multiplier, given as an optionally signed number. Unsigned numbers are taken as positively signed. No number at all implies 1 for a multiplier. Following a relative item by the string `ago' is equivalent to preceding the unit by a multiplier with value -1.
The string `tomorrow' is worth one day in the future (equivalent to `day'), the string `yesterday' is worth one day in the past (equivalent to `day ago').
The strings `now' or `today' are relative items corresponding to zero-valued time displacement, these strings come from the fact a zero-valued time displacement represents the current time when not otherwise change by previous items. They may be used to stress other items, like in `12:00 today'. The string `this' also has the meaning of a zero-valued time displacement, but is preferred in date strings like `this thursday'.

Recommended Repository Layout
While Subversion's flexibility allows you to lay out your repository in any way that you choose, we recommend that you create a trunk directory to hold the “main line” of development, a branches directory to contain branch copies,
and a tags directory to contain tag copies. For example:
$ svn list file:///var/svn/repos
/trunk
/branches
/tags
You'll learn more about tags and branches in Chapter 4, Branching and Merging. For details and how to set up multiple projects, see the section called “Repository Layout” and the section called “Planning Your Repository Organization” to read more about project roots.
You'll need the following build tools to compile Subversion:
* autoconf 2.58 or later (Unix only)
* libtool 1.4 or later (Unix only)
* a reasonable C compiler (gcc, Visual Studio, etc.)
Subversion also depends on the following third-party libraries:
* libapr and libapr-util (REQUIRED for client and server)
The Apache Portable Runtime (APR) library provides an
abstraction of operating-system level services such as file
and network I/O, memory management, and so on. It also
provides convenience routines for things like hashtables,
checksums, and argument processing. While it was originally
developed for the Apache HTTP server, APR is a standalone
library used by Subversion and other products. It is a
critical dependency for all of Subversion; it's the layer
that allows Subversion clients and servers to run on
different operating systems.
* SQLite (REQUIRED for client and server)
Subversion uses SQLite to manage some internal databases.
* libz (REQUIRED for client and server)
Subversion uses zlib for compressing binary differences.
These diff streams are used everywhere -- over the network,
in the repository, and in the client's working copy.
* libserf (OPTIONAL for client)
The Serf libraries both allow the Subversion client
to send HTTP requests. This is necessary if you want your
client to access a repository served by the Apache HTTP
server. There is an alternate 'svnserve' server as well,
though, and clients automatically know how to speak the
svnserve protocol. Thus it's not strictly necessary for your
client to be able to speak HTTP... though we still recommend
that your client be built to speak both HTTP and svnserve
protocols.
* OpenSSL (OPTIONAL for client and server)
OpenSSL enables your client to access SSL-encrypted https://
URLs (using libserf) in addition to unencrypted http:// URLs.
To use SSL with Subversion's WebDAV server, Apache needs to
be compiled with OpenSSL as well.
* Berkeley DB (OPTIONAL for client and server)
There are two different repository 'back-end'
implementations. One implementation stores data in a flat
filesystem (known as FSFS); the other implementation stores
data in a Berkeley DB database (known as BDB). When you
create a repository, you have the option of specifying a
storage back-end. The Berkeley DB back-end will only be
available if the BDB libraries are discovered at compile
time.
* libsasl (OPTIONAL for client and server)
If the Cyrus SASL library is detected at compile time, then
the svn client (and svnserve server) will be able to utilize
SASL to do various forms of authentication when speaking the
svnserve protocol.
* Python, Perl, Java, Ruby (OPTIONAL)
Subversion is mostly a collection of C libraries with
well-defined APIs, with a small collection of programs that
use the APIs. If you want to build Subversion API bindings
for other languages, you need to have those languages
available at build time.
* KDELibs, GNOME Keyring (OPTIONAL for client)
Subversion contains optional support for storing passwords in
KWallet (KDE 4) or GNOME Keyring.
