-/* 7zCommon.cpp: Implement 7z related classes and functions
- * Copyright (c) 2003 Jochen Tucht
- *
- * Remarks: Different versions of 7-Zip are interfaced through specific
- * versions of Merge7z (Merge7z311.dll, Merge7z312.dll, etc.)
- * WinMerge can either use an installed copy of the 7-Zip software,
- * or fallback to a local set of 7-Zip DLLs, which are to be included
- * in the WinMerge binary distribution.
- *
- * Fallback policies are as follows:
- *
- * 1. Detect 7-Zip version installed (XXX).
- * 2. If there is a Merge7zXXX.dll, be happy to use it
- * 3. Detect 7-Zip version from WinMerge distribution (YYY).
- * 4. If there is a Merge7zYYY.dll, be happy to use it.
- * 5. Sorry, no way.
- *
- * These rules can be customized by setting a registry variable
- * *Merge7z/Enable* of type DWORD to one of the following values:
- *
- * 0 - Entirely disable 7-Zip integration.
- * 1 - Use installed 7-Zip if present. Otherwise, use local 7-Zip.
- * 2 - Always use local 7-Zip.
- *
-
-Please mind 2. a) of the GNU General Public License, and log your changes below.

-DATE: BY: DESCRIPTION:
-========== ================== ================================================
-2003-12-09 Jochen Tucht Created
-2003-12-16 Jochen Tucht Properly generate .tar.gz and .tar.bz2
-2003-12-16 Jochen Tucht Obtain long path to temporary folder
-2004-01-20 Jochen Tucht Complain only once if Merge7z*.dll is missing
-2004-01-25 Jochen Tucht Fix bad default for OPENFILENAME::nFilterIndex
-2004-03-15 Jochen Tucht Fix Visual Studio 2003 build issue
-2004-04-13 Jochen Tucht Avoid StrNCat to get away with shlwapi 4.70
-2004-08-25 Jochen Tucht More explicit error message
-2004-10-17 Jochen Tucht Leave decision whether to recurse into folders
- to enumerator (Mask.Recurse)
-2004-11-03 Jochen Tucht FIX [1048997] as proposed by Kimmo 2004-11-02
-2005-01-15 Jochen Tucht Read 7-Zip version from 7zip_pad.xml
- Set Merge7z UI language if DllBuild_Merge7z >= 9
-2005-01-22 Jochen Tucht Better explain what's present/missing/outdated
-2005-02-05 Jochen Tucht Fall back to IDD_MERGE7ZMISMATCH template from
- .exe if .lang file isn't up to date.
-2005-02-26 Jochen Tucht Add download link to error message
-2005-02-26 Jochen Tucht Use WinAPI to obtain ISO language/region codes
-2005-02-27 Jochen Tucht FIX [1152375]
-2005-04-24 Kimmo Varis Don't use DiffContext exported from DirView
-2005-06-08 Kimmo Varis Use DIFFITEM, not reference to it (hopefully only
- temporarily, to sort out new directory compare)
-2005-06-22 Jochen Tucht Change recommended version of 7-Zip to 4.20
- Remove noise from Nagbox
-2005-07-03 Jochen Tucht DIFFITEM has changed due to RFE [ 1205516 ]
-2005-07-04 Jochen Tucht New global ArchiveGuessFormat() checks for
- formats to be handled by external command line
- tools. These take precedence over Merge7z
- internal handlers.
-2005-07-05 Jochen Tucht Move to Merge7z::Format::GetDefaultName() to
- build intermediate filenames for multi-step
- compression.
-2005-07-15 Jochen Tucht Remove external command line tool integration
- for now. Rethink about it after 2.4 branch.
-2005-08-20 Jochen Tucht Option to guess archive format by signature
- Map extensions through ExternalArchiveFormat.ini
-2005-08-23 Jochen Tucht Option to entirely disable 7-Zip integration
-2007-01-04 Kimmo Varis Convert using COptionsMgr for options.
-2007-06-16 Jochen Neubeck FIX [1723263] "Zip --> Both" operation...
-2007-12-22 Jochen Neubeck Fix Merge7z UI lang for new translation system
- Change recommended version of 7-Zip to 4.57
-2010-05-16 Jochen Neubeck Read 7-Zip version from 7z.dll (which has long
- ago replaced the various format and codec DLLs)
- Change recommended version of 7-Zip to 4.65

+ * Fallback policies are as follows:\r
+ *\r
+ * 1. Detect 7-Zip version installed (XXX).\r
+ * 2. If there is a Merge7zXXX.dll, be happy to use it\r
+ * 3. Detect 7-Zip version from WinMerge distribution (YYY).\r
+ * 4. If there is a Merge7zYYY.dll, be happy to use it.\r
