executes “make” and “dpkb-deb” in sequence to finish its job.

dm.pl: building package `com.iosre.iosreproject' in `./com.iosre.iosreproject_0.0.1-

7_iphoneos-arm.deb'.

“make package” has created a “com.iosre.iosreproject_0.0.1-7_iphoneos-arm.deb” file,

which is ready to be published.

There is another important function of “make package” command. After executing this

command, besides “obj” folder, another “_” folder is also created as shown below.
