This script generates 2 lists of NSIS commands (install&uninstall)
for all files in a given directory
Usage:
gen_list_files_for_nsis.py <dir src> <inst list> <uninst list>
Where
<dir src> : dir with sources; must exist
<inst list> : list of files to install (NSIS syntax)
<uninst list> : list of files to uninstall (NSIS syntax)
(both these will be overwriten each time)

# os.path.walk(path, visit, arg)
#~ Calls the function visit with arguments (arg, dirname, names) for each directory
#~ in the directory tree rooted at path (including path itself, if it is a directory).
#~ The argument dirname specifies the visited directory, the argument names lists
#~ the files in the directory (gotten from os.listdir(dirname)). The visit function
#~ may modify names to influence the set of directories visited below dirname,
#~ e.g., to avoid visiting certain parts of the tree. (The object referred to by names
#~ must be modified in place, using del or slice assignment.)
