&app; is a free software package designed to help you with
genealogical research. It allows you to store, edit, and research
genealogical data using your computer. &app; is an open source
software package, which means you are free to run it on any number
of computers, examine the code, make changes, and redistribute as
many copies as you like. It is developed and maintained by a
worldwide team of volunteers and is available at no cost from the
project web site and from many software distributions

<para>GRAMPS is a software package designed for genealogical
research. Although similar to other genealogical programs, GRAMPS
offers some unique and powerful features, which we'll discuss
below. </para>

<title>Why use GRAMPS?</title>
<para>
Most genealogy programs allow the researcher to input
information related to a family tree. They can usually display
descendant or ancestral relationships through graphical
displays, charts, or reports. Some allow pictures or other media
to be inserted to enhance the raw data. Most provide a means to
include data on individuals or families that may or may not be
related to the primary family being researched. And they may
include other features such as exporting or importing to and
from other programs and printing data contained in various
reports.
<para>Most genealogy programs allow you to enter information
about your ancestors and descendants. Typically, they can
display family relationships through charts, graphs, or
reports. Some allow you to include pictures or other media. Most
let you include information about people even if those people
are not related to the primary family you happen to be
researching. And they may include features that let you exchange
data with other programs and print different types of
reports. </para>
</para><para>
<para>GRAMPS has all these capabilities and more. Notably, it
allows you to integrate bits and pieces of data as they arise
from your research and to put them in one place &mdash; your
computer. You can then use your computer to manipulate,
correlate, and analyze your data, rather than messing with reams
of paper. </para>

<title>What's new since 1.0.X</title>
<para>
This section lists most notable changes from the previous
stable branch of &app;, the 1.0.X.

</para>
<para>If you are new to GRAMPS, it may not be important for you
to know how GRAMPS version 2.0.0 (the object of this manual)
differs from previous versions of the software. You may
therefore elect to skip this section.</para>
<para>However, if you are already familiar with GRAMPS and are
interested in the new aspects and features of version 2.0.0,
please read on.</para>

<varlistentry><term>Berkeley database backend</term>
<listitem>
<para>
The default format for &app; is now the BSDDB database.
This change allowed us to overcome performance issues and
memory requirements of the 1.0.X branch. With the database
backend, the database sizes of up to a hundred thousand
people do not present a major obstacle any longer.
<para>We've adopted the Berkeley database format (BSDDB) as
the default for GRAMPS. Berkeley is the most widely used
open source developer database in the world.</para>

The default extension for &app; BSDDB database files is
grdb. The new format is open and fully documented in the
developer's API reference distributed with the source of
&app;.

<title>Preferred format</title>
A consequence of the new database backend is that the
changes, once approved by the user, are applied
immediately. In short, once you click
<guibutton>OK</guibutton> in the Person, Family, Source,
Place, Media object, or Event editor, all the changes made
to this object are recorded in the database. No saving is
necessary (or even possible). The analog of quitting
without saving would be abandoning all changes and
quitting. Also, it is possible to undo recent actions.

<para>A consequence of the new database back-end is that the

Place, Media object, or Event editor immediately records
changes in the database. </para>
<para>In previous versions, you could &quot;quit without
saving.&quot; This option no longer exists per se; however,
in version 2.0.0, you can achieve the same effect if you
abandon or &quot;cancel&quot; all changes and then
quit.</para>

<para>Along with the BSDDB backend, we've incorporated
&quot;in-memory&quot; database handling for the GRAMPS XML
and GEDCOM formats. This means you can now open files in
those two formats and work with their data without having to
first create a new database and import data into it. Since
this approach requires GRAMPS to hold all the data in
memory, it is only useful for small databases (depending on
available memory size).</para>
There were numerous changes in the interface. Most of them
are subtle and incremental improvements, and all of them
cannot be listed here. The most noticeable changes are:

<para>
Along with the BSDDB backend, the in-memory database handling
for &app; XML and GEDCOM formats has been added. Simply put, it
is now possible to natively open data in those two formats
(although the preferred and default format is grdb) and work with
that data, without necessarily setting up an empty database and
then importing into it. This approach requires holding all data in
memory, so it is only useful for small databases (depending on the
available memory size). In such mode, the data is automatically
saved upon exit, to mimic the functionality of the real database.

<para>We've improved the way GRAMPS integrates with the GNOME
desktop interface common to many Linux distributions. All file
formats recognized by GRAMPS are now registered as mime types;
each has its own icon and has GRAMPS as its default
handler. Thus, if you double-click on any file having one of
these formats, GRAMPS will launch and open the file.</para>
<para>We've also added support for GNOME's &quot;recent
documents&quot; function and have incorporated this function
within GRAMPS itself.</para>

An overall change of the whole report framework has been
accomplished. All reports now remember their options. It
is possible to generate reports from the command line,
without launching the interactive &app; session. The
report API is much simpler now, making it easy to write a
custom report. A single code instance may be used for a
standalone report, a book item, and a command-line
report.

program new ways of displaying names, as may be required
by various cultures and languages.
