     Type:  Bugs                     |      Status:  new       
Milestone:  To Be Determined         |   Component:  filesystem
  Version:  Boost 1.45.0             |    Severity:  Problem   
 Keywords:  extension                |  
-------------------------------------+--------------------------------------
 1. From Reference (see
 http://www.boost.org/doc/libs/1_45_0/libs/filesystem/v3/doc/reference.html

 #path-replace_extension):

 {{{
 path& replace_extension(const path& new_extension = path());

 Postcondition: extension() == replacement,
 where replacement is new_extension
   if new_extension.empty() || new_extension[0] == the dot character,
 otherwise replacement is the dot character followed by new_extension.

 Returns: *this
 }}}
 Testing this behavior
 {{{
 path ph("foo.txt");
 std::cout << ph.replace_extension("exe");
 }}}
 Output:
 {{{
 foo
 }}}
 Eather change the Reference or fix it in code.

 2. Current implementation doesn't allow to work with complex extentions.

 {{{
 path ph("foo.txt");
 std::cout << ph.replace_extention(".tar.bz2");
 }}}
 Output:
 {{{
 foo.bz2
 }}}

 3. There is no function to just add extension.
 something like that:
 {{{
 path ph("foo.txt");
 std::cout << ph.add_extension("bz2");
 }}}
 Expected output:
 {{{
 foo.txt.bz2
 }}}
