platform. It uses a UNIX emulation layer which might be a bit
slower compared to the native Win32 tools, but at an acceptable
level. The installation and update is pretty easy and done
through a single (web based) setup.exe.</p><p>The native Win32 tools will typically be a bit faster,
but more complicated to install, as you would have to download
the tools from different webpages, and install them in
different ways, tweaking the PATH and alike.</p><div class="note" title="Note!" style="margin-left: 0.5in; margin-right: 0.5in;"><table border="0" summary="Note: Note!"><tr><td rowspan="2" align="center" valign="top" width="25"><img alt="[Note]" src="wsdg_graphics/note.png"></td><th align="left">Note!</th></tr><tr><td align="left" valign="top"><p>As there's no Win32 native bash version available, at
least a basic installation of cygwin is required in any
case.</p></td></tr></table></div><p>Although Cygwin consists of several separate packages,
the installation and update is done through a single setup.exe,
which acts similar to other web based installers. All tools
will be installed into one base folder, the default is
<code class="filename">C:\cygwin</code>.</p><p>You will find this network based setup.exe at:
<a class="ulink" href="http://www.cygwin.com/" target="_top">http://www.cygwin.com/</a>. Click on one of the
"Install Cygwin now" appearances to download the
<code class="filename">setup.exe</code>. After the download completed,
start this
<code class="filename">setup.exe</code> on your machine.</p><p>The setup will ask you for some settings, the defaults
should usually work well for a first start. At the "Select
Packages" page, you'll need to select some additional packages,
which are not installed by default. Navigate to the required
Category/Package row and click on the "Skip" item in the "New"
column so it shows a version number for the required
package</p><p>After clicking the Next button several times, the setup
will then download and install the selected packages (this may
take a while, depending on the package size).</p><p>Under: "Start→Programs→Cygwin→Cygwin
Bash Shell" you should now be able to start a new Cygwin bash
shell, which is similar to the command line
(command.com/cmd.exe) in Win32, but much more powerful.</p><div class="section" title="4.2.1.

Add/Update/Remove Cygwin Packages</h3></div></div></div><p>If you want to add additional, update installed or
remove packages later, you have to start the setup.exe again.
At the "Select Packages" page, the entry in the "New" column
will control what is done (or not) with the package. If a new
version of a package is available, the new version number
will be displayed, so it will be automatically updated. You
can change the current setting by simply clicking at it, it
will change between:
