[Lazarus] program version

[Antonio Fortuny]

Hi folks.

First of all happy new year 2012.

Lazarus provides the possibility to include the program version in the 
project options. I've the ability to extract it at runtime using the 
WIndows core functions GetFileVersionInfoSize, GetFileVersionInfo and 
VerQueryValue.
I would like to know if there is an equivalent in Linux systems.

Antonio.
