How can I install Roundcube with skin elastic on DirectAdmin server?

** As of November, 25th RoundCube Webmail 1.4.x can be installed by DirectAdmin/CustomBuild without need to customize it **

If you would like to install the skin elastic for Roundcube, here is short guide on how to do it on DirectAdmin server using a pre-release of the webmail.

Installation instructions

Let's go and download an archive with the Roundcube Webmail:

cd /usr/local/directadmin/custombuild
wget https://github.com/roundcube/roundcubemail/releases/download/1.4-rc2/roundcubemail-1.4-rc2-complete.tar.gz -O roundcubemail-1.4-rc2.tar.gz

Now we need to install it:

cd /usr/local/directadmin/custombuild
echo 'roundcubemail:1.4-rc2:1a0fc8125607734cdc6db12205ac5a13' >> custom_versions.txt
./build roundcube

and then change a skin:

mkdir -p /usr/local/directadmin/custombuild/custom/roundcube/
perl -pi -e 's/larry/elastic/' /var/www/html/roundcube/config/config.inc.php
cp -p /var/www/html/roundcube/config/config.inc.php /usr/local/directadmin/custombuild/custom/roundcube/

That's it.
