	----- Change log -----
	20090131: v0.1.0 released
	* Some minor things have still to be done.
	* Mounting ewf as dd: Seems to work. Diff didn't complain about
	changes between original dd and emulated dd.
	* Mounting ewf as vdi: Seems to work too. VBox accepts the emulated
	vdi as valid vdi file and I was able to mount the containing fs
	under Debian. INFO: Debian freezed when not using mount -r !!
	20090203: v0.1.1 released
	* Multiple code improvements. For ex. cleaner vdi header allocation.
	* Fixed severe bug in image block calculation. Didn't check for odd
	input in conversion from bytes to megabytes.
	* Added more debug output
	20090210: v0.1.2 released
	* Fixed compilation problem (Typo in image_init_info() function).
	* Fixed some problems with the debian scripts to be able to build
	packages.
	* Added random generator initialisation (Makes it possible to use
	more than one image in VBox at a time).
	20090215: * Added function init_cache_blocks which creates / loads a cache
	file used to implement virtual write capability.
	20090217: * Implemented the fuse write function. Did already some basic tests
	with dd and it seems to work. But there are certainly still some
	bugs left as there are also still some TODO's left.
	20090226: * Changed program name from mountewf to xmount.
	* Began with massive code cleanups to ease full implementation of
	virtual write support and to be able to support multiple input
	image formats (DD, EWF and AFF are planned for now).
	* Added defines for supported input formats so it should be possible
	to compile xmount without supporting all input formats. (DD
	input images are always supported as these do not require any
	additional libs). Input formats should later be en/disabled
	by the configure script in function to which libs it detects.
	* GetOrigImageSize function added to get the size of the original
	image whatever type it is in.
	* GetOrigImageData function added to retrieve data from original
	image file whatever type it is in.
	* GetVirtImageSize function added to get the size of the virtual
	image file.
	* Cleaned function mountewf_getattr and renamed it to
	GetVirtFileAttr
	* Cleaned function mountewf_readdir and renamed it to GetVirtFiles
	* Cleaned function mountewf_open and renamed it to OpenVirtFile
	20090227: * Cleaned function init_info_file and renamed it to
	InitVirtImageInfoFile
	20090228: * Cleaned function init_cache_blocks and renamed it to
	InitCacheFile
	* Added LogMessage function to ease error and debug logging (See
	also LOG_ERROR and LOG_DEBUG macros in xmount.h)
	* Cleaned function init_vdi_header and renamed it to
	InitVirtVdiHeader
	* Added PrintUsage function to print out xmount usage informations
	* Cleaned function parse_cmdline and renamed it to ParseCmdLine
	* Cleaned function main
	* Added ExtractVirtFileNames function to extract virtual file names
	from input image name
	* Added function GetVirtImageData to retrieve data from the virtual
	image file. This includes reading data from cache file if virtual
	write support is enabled.
	* Added function ReadVirtFile to replace mountewf_read
	20090229: * Fixed a typo in virtual file name creation
	* Added function SetVirtImageData to write data to virtual image
	file. This includes writing data to cache file and caching entire
	new blocks
	* Added function WriteVirtFile to replace mountewf_write
	20090305: * Solved a problem that made it impossible to access offsets >32bit
	20090308: * Added SetVdiFileHeaderData function to handle virtual image type
	specific data to be cached. This makes cache files independent
	from virtual image type
	20090316: v0.2.0 released
	20090327: v0.2.1 released
	* Fixed a bug in virtual write support. Checking whether data is
	cached didn't use semaphores. This could corrupt cache files
	when running multi-threaded.
	* Added IsVdiFileHeaderCached function to check whether VDI file
	header was already cached
	* Added IsBlockCached function to check whether a block was already
	cached
	20090331: v0.2.2 released (Internal release)
	* Further changes to semaphores to fix write support bug.
	20090410: v0.2.3 released
	* Reverted most of the fixes from v0.2.1 and v0.2.2 as those did not
	solve the write support bug.
	* Removed all semaphores
	* Added two pthread mutexes to protect virtual image and virtual
	info file.
	20090508: * Configure script will now exit when needed libraries aren't found
	* Added support for newest libewf beta version 20090506 as it seems
	to reduce memory usage when working with EWF files by about 1/2.
	* Added LIBEWF_BETA define to adept source to new libewf API.
	* Added function InitVirtualVmdkFile to build a VmWare virtual disk
	descriptor file.
	20090519: * Added function CreateVirtDir implementing FUSE's mkdir to allow
	VMWare to create his <iname>.vmdk.lck lock folder. Function does
	not allow to create other folders!
	* Changed cache file handling as VMDK caching will need new cache
	file structure incompatible to the old one.
	20090522: v0.3.0 released
	* Added function DeleteVirtFile and DeleteVirtDir so VMWare can
	remove his lock directories and files.
	* Added function RenameVirtFile because VMWare needs to rename his
	lock files.
	* VMDK support should work now but descriptor file won't get cached
	as I didn't implement it yet.
	20090604: * Added --cache commandline parameter doing the same as --rw.
	* Added --owcache commandline parameter doing the same as --rw but
	overwrites any existing cache data. This can be handy for
	debugging and testing purposes.
	* Added "vmdks" output type. Same as "vmdk" but generates a disk
	connected to the SCSI bus rather than the IDE bus.
	20090710: v0.3.1 released
	20090721: * Added function CheckFuseAllowOther to check wether FUSE supports
	the "-o allow_other" option. It is supported when
	"user_allow_other" is set in /etc/fuse.conf or when running
	xmount as root.
	* Automatic addition of FUSE's "-o allow_other" option if it is
	supported.
	* Added special "-o no_allow_other" command line parameter to
	disable automatic addition of the above option.
	* Reorganisation of FUSE's and xmount's command line options
	processing.
	* Added LogWarnMessage function to output a warning message.
	20090722: * Added function CalculateInputImageHash to calculate an MD5 hash
	of the first input image's HASH_AMOUNT bytes of data. This hash is
	used as VDI creation UUID and will later be used to match cache
	files to input images.
	20090724: v0.3.2 released
	20090725: v0.4.0 released
	* Added AFF input image support.
	* Due to various problems with libewf and libaff packages (Mainly
	in Debian and Ubuntu), I decided to include them into xmount's
	source tree and link them in statically. This has the advantage
	that I can use whatever version I want.
	20090727: v0.4.1 released
	* Added again the ability to compile xmount with shared libs as the
	Debian folks don't like the static ones :)
	20090812: * Added TXMountConfData.OrigImageSize and
	TXMountConfData.VirtImageSize to save the size of the input and
	output image in order to avoid regetting it always from disk.
	20090814: * Replaced all malloc and realloc occurences with the two macros
	XMOUNT_MALLOC and XMOUNT_REALLOC.
	20090816: * Replaced where applicable all occurences of str(n)cpy or
	alike with their corresponding macros XMOUNT_STRSET, XMOUNT_STRCPY
	and XMOUNT_STRNCPY pendants.
	20090907: v0.4.2 released
	* Fixed a bug in VMDK lock file access. glob_vmdk_lockfile_size
	wasn't reset to 0 when the file was deleted.
	* Fixed a bug in VMDK descriptor file access. Had to add
	glob_vmdk_file_size to track the size of this file as strlen was
	a bad idea :).
	20100324: v0.4.3 released
	* Changed all header structs to prevent different sizes on i386 and
	amd64. See xmount.h for more details.
	20100810: v0.4.4 released
	* Found a bug in InitVirtVdiHeader(). The 64bit values were
	addressed incorrectly while filled with rand(). This leads to an
	error message when trying to add a VDI file to VirtualBox 3.2.8.
	20110210: * Adding subtype and fsname FUSE options in order to display mounted
	source in mount command output.
	20110211: v0.4.5 released
	20111011: * Changes to deal with libewf v2 API (thx to Joachim Metz)
	20111109: v0.4.6 released
	* Added support for DMG output type (actually a DD with .dmg file
	extension). This type is used as default output type when
	using xmount under Mac OS X.
	20120130: v0.4.7 released
	* Made InitVirtImageInfoFile less picky about missing EWF infos.
	20120507: * Added support for VHD output image as requested by various people.
	* Statically linked libs updated to 20120504 (libewf) and 3.7.0
	(afflib).
	20120510: v0.5.0 released
	* Added stbuf->st_blocks calculation for VHD images in function
	GetVirtFileAttr. This makes Windows not think the emulated
	file would be a sparse file. Sparse vhd files are not attachable
	in Windows.
	20130726: v0.6.0 released
	* Added libaaff to replace libaff (thx to Guy Voncken).
	* Added libdd to replace raw dd input file handling and finally
	support split dd files (thx to Guy Voncken).
	20140311: * Added libaewf (thx to Guy Voncken).
	20140726: * Added support for dynamically loading of input libs. This should
	ease adding support for new input image formats in the future.
	* Moved input image functions to their corresponding dynamically
	loadable libs.
	* Prepended "glob_" to all global vars for better identification.
	20140731: * Added --offset option as requested by HPM.
	* Began massive code cleanup.
	20140803: * Added correct return code handling when calling input lib
	functions including getting error messages using GetErrorMessage.
	* Added input lib specific option parsing.
	* Re-implemented InitVirtImageInfoFile() using input lib's
	GetInfofileContent() function.
	* Further code cleanups.
	20140807: * Further code cleanups.
	* Renamed GetVirtFileAttr() to FuseGetAttr()
	* Renamed CreateVirtDir() to FuseMkDir()
	* Renamed CreateVirtDir() to FuseMkNod()
	* Renamed OpenVirtFile() to FuseOpen()
	* Renamed GetVirtFiles() to FuseReadDir()
	* Renamed ReadVirtFile() to FuseRead()
	* Renamed RenameVirtFile() to FuseRename()
	* Renamed DeleteVirtDir() to FuseRmDir()
	* Renamed DeleteVirtFile() to FuseUnlink()
	* Renamed WriteVirtFile() to FuseWrite()
	* Fixed bug in CalculateInputImageHash() where always HASH_AMOUNT
	bytes were hased even if input image is smaller.
	* Fixed a newly introduced bug in FuseRead() and GetVirtImageData()
	returning -EIO when trying to read behind EOF. The correct return
	value is 0.
	20140811: * Renamed CheckFuseAllowOther() to CheckFuseSettings() and added a
	check to see if user is part of the fuse group.
	20140814: * Replaced cuserid() with getpwuid(geteuid()) in CheckFuseSettings()
	as it is deprecated on Linux and not available on OSx.
	* Only build fuse group checks from CheckFuseSettings() on Linux.
	20140820: * Added libxmount_morphing handling.
	* Renamed LoadInputLibs() to LoadLibs() and added code to find and
	load morphing libs.
	* Added FindMorphingLib() function.
	20140821: * Changed command line syntax to support specification of multiple
	input images of different types.
	* Added code in main() to initialize and open multiple input images.
	* Added GetMorphedImageSize() and GetMorphedImageData().
	20140822: * Removed GetInputImageSize() as it isn't needed anymore.
	* Quick test showed morphing using libxmount_morphing_combine seems
	to work.
	20140825: * Added InitResources() and FreeResources() functions.
	20140926: v0.7.0 released
	20140930: v0.7.1 released
	* Fixed bug with --sizelimit command line option.
	20141001: v0.7.2 released
	* Fixed bug in FreeResources(). Do not free vdi.p_vdi_block_map as
	it is part of vdi.p_vdi_header.
	20141113: v0.7.3 released
	* Fixed minor bug in ParseCmdLine() which was not checking upper
	argc bounds correctly.
	20150820: v0.7.4 released
	20150901: * Improved the way fsname is built
