also rename wchar -> utf8 to avoid conflict with <wchar.h> (requires
rebuild of workspace)
(unfortunately copying history fails to "502 bad gateway"; had to delete
old + add new independently)
This was SVN commit r7340.
archive: ArchiveEntry now a mememto and not exposed directly
typedefs for boost::shared_ptr
fixed up dir_util to new interface
add "FileProvider" that does Load/Store and indicates Precedence
vfs: structure has changed. one RealDirectory per OS dir; vfs_tree
stores it; populate uses it to Add() stuff to vfs_tree; lookup does path
traversal and calls populate
This was SVN commit r5499.
archive: pretty much done except for trace and archive_builder
IO: io_manager still needs to be fixed/revised (especially WRT buffer
and alignment management)
posix: done
vfs: need to complete vfs_mount and tie it in to vfs.cpp
dir_util: needs further revisions (VFS interface changed since then)
This was SVN commit r5475.
