+//! Print version information about the program and package.
+//!
+//! The program name is taken from fName. If a leading "lt-" is found,
+//! it is removed. This is useful if the program was build and run
+//! using libtool.
+//!
+//! The package name is taken from the define PACKAGE_STRING. If it is
+//! not defined (like automatically done by autoconf) no package information
+//! is printed. The same is true for PACKAGE_URL and PACKAGE_BUGREPORT.
+//!
+//! From help2man:
+//!
+//! The first line of the --version information is assumed to be in one
+//! of the following formats:
+//!
+//! \verbatim
+//!  - <version>
+//!  - <program> <version>
+//!  - {GNU,Free} <program> <version>
+//!  - <program> ({GNU,Free} <package>) <version>
+//!  - <program> - {GNU,Free} <package> <version>
+//! \endverbatim
+//!
+//!  and separated from any copyright/author details by a blank line.
+//!
+//! Handle multi-line bug reporting sections of the form:
+//!
+//! \verbatim
+//!  - Report <program> bugs to <addr>
+//!  - GNU <package> home page: <url>
+//!  - ...
+//! \endverbatim
+//!
+//! @param name
+//!     name of the program (usually argv[0]). A possible leading "lt-"
+//!     is removed.
