+ Creates an image for DB2 Express-C v10.5
+
+ The packages for DB2 Express-C can be downloaded from:
+ http://www-01.ibm.com/software/data/db2/express-c/download.html
+ and click on the link "DB2 Express-C for Linux 64-bit".
+ New users can either get an IBM ID or click on the "Proceed without an
+ IBM ID". User is provided with a registration form which needs to be
+ completed in order to proceed further to download the DB2 Express-C
+ packages. After accepting the license agreement, user can download the
+ the DB2 Express-C package (.tar.gz file).
+
+ There are 2 options for making the DB2 Express-C package accessible to
+ the Trove disk-image building process:
+  - place the package in a private repository and set the environment
+    variable DATASTORE_PKG_LOCATION with the url to this private
+    repository.
+    e.g. export DATASTORE_PKG_LOCATION="http://www.foo.com/db2/v10.5_linuxx64_expc.tar.gz"
+
+  - download the package and place it in any directory on the local
+    filesystem that the trove-integration scripts can access. Set the
+    environment variable DATASTORE_PKG_LOCATION with the full path to
+    the downloaded package.
+    e.g. export DATASTORE_PKG_LOCATION="/home/stack/db2/v10.5_linuxx64_expc.tar.gz"
+
+ The environment variables used are as follows:
+
+ DATASTORE_PKG_LOCATION - is the place where user stores the DB2
+             Express-C package after registration. This can either be a
+             url to a private repository or the full path to the
+             downloaded package on a local filesystem.
+ DATASTORE_DOWNLOAD_OPTS - defines any wget options user wants to specify
+             like user,password, etc. This is an optional variable and is
+             needed only if specifying a private repository to download
+             the packages from.
+    e.g. export DATASTORE_DOWNLOAD_OPTS="--user=foo --password='secret'"
+
