Build the application and create the package.\n\

Usage:\n\
10+
$(basename "$0") [-b bld_dir] [-p pkg_dir] [-q qmake] [-s suffix] [-v version]\n\
11+
\n\
12+
Options:\n\
13+
-b bld_dir The directory where the application will be built.\n\
14+
By default it is <source_root>/build\n\
15+
-p pkg_dir The directory where the package will be built.\n\
16+
By default this is <bld_dir>/<pkg_name>_<pkg_version>\n\
17+
-q qmake The name or full path of the qmake utility. In some\n\
18+
distributives, qmake for Qt 6 is named qmake6.\n\
19+
-s suffux The suffix that will be added to the package name after the\n\
20+
version and before the architecture type.\n\
21+
Nothing is added by default.\n\
22+
-v version Define the package version. By default version gettings from\n\
23+
the version.h file.\n\
24+
\n\
25+
It is assumed that the necessary dependencies and tools are already installed\n\
26+
in the system.\n\
27+
\n\
28+
The created package is saved in the current working directory.\
