wiki "for the impatient" section

[karan singh malhi <ka...@verizon.net>]

The "for the impatient" section  of the wiki has the following
instructions

$ svn checkout http://svn.apache.org/repos/asf/geronimo/trunk geronimo
        $ cd geronimo
        $ svn update
        $ maven
        $ mkdir target
        $ (cd target && jar xf ~/.maven/repository/geronimo/jars/geronimo-assembly-1.0-SNAPSHOT.jar)
        $ java -jar target/bin/server.jar org/apache/geronimo/Server

My question is , why do i have to create  a target folder , when i can simply run the server by
~/geronimo/modules/assembly/target/geronimo-1.0-SNAPSHOT/bin deployer.jar org/apache/geronimo/Server

Since i am planning to update the wiki for newbies, i would like to know if i am missing something
and why i should create the target folder?

Thanks

karan
