 # Description: a development version of builder.sh. Read S;Z
 # documentation (README.org and dev_patches.org) before use it.
 # This script just contains functions that automates the build and
 # test processes at development phases, so, function names and
 # "status" function messages are autoexplicative. Read them too.
