+
+	FAT32 partition contiguous file space manager.
+	Creating, checking or copying contiguous, not-fragmented files.
+	Command line utility for Linux and Windows platforms.
+	
+	Features:
+	
+		* Checks if file can be created contiguous before 
+		  begining to copy the data, by default. 
+		  Usefull for limiting the wear of the flash memory on the USB 
+		  connected devices.
+
+		* Can be used to check if the files on the disk are already 
+		  contiguous or not.
+		  Providing contiguous, non-fragmented files can be necessary
+		  for a hardware that has limited capabilities of reading the 
+		  data from the FAT32 partitions.
+
+		* Can be used to open system disks or disk image files.
+		  (Administrator or root level privileges are usually required,
+		  depending on the disk type, operating system type or version.)
+		  
+		* Can be configured to run only from the actual shell, with 
+		  no need of entering the internal micro shell otherwise.
+		  See the '--run_cmd' switch or the 'scr' internal command.
+
+
+	This project makes use of the FatFs library that
+	enables reading and writing files on the FAT32 disks
+	(see the Links section for more info).
+
+
+WARNING!
+---------------------
+
+	USE AT YOUR OWN RISK!
+	NO WARRANTY PROVIDED!
+	BACKUP YOUR DATA FIRST!
+
+
+Command line interface
+-----------------------------
+
+	--open_disk DISKNAME
+		
+		Open disk on the program startup.
+		DISKNAME can be:
+		* File name of the FAT32 partition image.
+		* System name of the partition on the physical HDD/SDD.
+		  Eg. on Linux this may be "/dev/sdd2".
+		  
+		Note that this is an optional switch and the disk can be always 
+		opened with the "open" command from the program's micro shell.
+		
+	--read_only
+		
+		Open the disk in read only mode.
+		This affect both, the "--open_disk" switch 
+		and the "open" command.
+		
+	--current_dir PATH
+		
+		Directory on the opened disk to srart in.
+		Valid only when opening disk on startup with the "--open_disk" switch.
+
+	--error_exit
+	
+		Exit the program when command error occuts.
+		Usefull when the program is running text script via the "scr" command.
+
+	--buff_rw_size NUM
+
+		Buffer size for read and write operations. Default is 1MiB.
+		For debug purposes.
+		
+	--run_cmd CMD
+		
+		Run command on the program startup.
+		Can be used for automation from the shell.
+		See "scr" command on how to execute commands from text file.
+
+	--crc_ul TEXT
+		
+		Utility. 
+		Generates checksum that goes into the "ul.cfg" file and the ties game entry
+		with the game split-files. USB Advance and OpenPS2Loader (OPL) format.
+		This is so that you can manually create and copy files to the disk,
+		For example, for game title "New Playstation Game", final file
+		name may endup being: ul.88BC6456.SLUS_123.45.00
+		
+
+	--ul_cfg_add TEXT
+		
+		Utility. Opens "ul.cfg" file in current system direntory, 
+		adds entry froom text eneterd, and exits the program.
+		The TEXT sould contain game name followed by game id.
+		Game id can be with or without the punctuation. Either 
+		SLUS12345 or SLUS_123.45 is expected.
+		Eg. if the TEXT is set to "New Playstation Game SLUS_123.45",
+		added will be game with name set to "New Playstation Game"
+		and game-id set to "SLUS_123.45".
+		Note 1: This is only a command line switch that makes the 
+				program exit after it's done - does not starts the main program.
+		Note 2: No game files are opened or copied when using this switch.
+
+	--no_disk_reinit_w
+		
+		Do not reinit the disk at the end of all write operations, like 
+		injecting a file using the "inj" command.
+	
+	--write_sync
+		
+		For debug purposes.
+		Performs a sync operation on each buffer write.
+		
+
+Micro shell interface
+------------------------------
+
+	This is just simple command line interpreter that parses user 
+	input from the STDIN in the console/terminal.
+	Once started, enter "help" or "list" to get more info.
+	Enter "help all" to show list and info for all commands.
+
+Commands
+--------------------
+
+	>>> open <<<
+	Opens FAT32 disk, partition or disk image.
+	Use -r switch to open in the read-only mode.
+
+	>>> close <<<
+	Closes current, previously opened disk.
+
+	>>> ls <<<
+	Alias: dir
+	Shows contents of current directory.
+	Use '-l' switch to get long listing.
+	Use '-f' switch to show fragmentation for each file.
+
+	>>> cd <<<
+	Changes current directory.
+	Use 'cd ..' to switch to the parent directory.
+	Use 'cd /' to switch to the root directory.
+
+	>>> pwd <<<
+	Shows current directory path.
+
+	>>> diskinfo <<<
+	Alias: dinf
+	Shows basic disk information.
+	Size, empty space, label, etc.
+
+	>>> exit <<<
+	Aliases: quit, q
+	Exits the program and returns to the shell.
+
+	>>> dele <<<
+	Deletes single file or empty-directory.
+	Will not delete files with read-only flag
+	or non-empty directories.
+	Use '-f' switch to force delete of read-only file.
+
+	>>> mkfile <<<
+	Alias: mkf
+	Creates new file. Empty or with prealocated size.
+	File is created contiguous, with contents undefined.
+	Use '-s SIZE' switch to specify its size.
+	Fails if there is not enough contiguous space available.
+
+	>>> extr <<<
+	Copies file from curently mounted disk to the system.
+	Syntax: extr <source> <dest>.
+
+
+	>>> inj <<<
+	Copies file from the system to the currently opened disk.
+	By default, new file is being created contiguous.
+	Fails if there is not enouh contiguous space on the disk.
+	Use '-o' switch to allow file to be created non-contiguous.
+	Syntax: inj [-o] <source> [<dest>]
+	If <dest> is omited, new file name is automatically taken from the path in <source>.
+	If the file name in <dest> is without the path part, creates file in the current directory.
+
+	>>> showfrag <<<
+	Alias: sfr
+	Shows the file fragmentation.
+	Syntax: showfrag <file-name>
+	This command is limited in that it can only tell if the file is fragmented or not.
+	If retrieved value of is 1 then the file is not fragmented, contiguous.
+	If the file is fragmented, the value shown is '2+'.
+	Note: you can also use the 'ls -f' command.
+
+	>>> scr <<<
+	Alias: s
+	Runs commands from the text script - file on the system.
+	Syntax: scr [-c] <file-name>
+	File name is expected to be an ANSI or UTF-8 text file.
+	Use '-c' switch to continue executing on errors.
+	This command can be used to automate tasks from the actual shell.
+	For shell automation, consider command line switches: '--run_cmd'
+	and '--error_exit'.
+	If file name is without the extension, auto checks for the TXT file.
+
+	>>> show_disks <<<
+	Alias: sd
+	Shows system disks or volumes.
+	Use the 'open' command to open diisk from the list.
+	For example, to open disk D, use 'open D:' command.
+	On unix platforms use device names from the /dev directory.
+	Example: 'open /dev/sdc1'.
+
+	>>> ul_inject <<<
+	Alias: uli
+	Injects ISO adding entry to the 'ul.cfg' file.
+	Asks to press Enter key once files allocated, before file copy.
+	WARNING: does not checks if the same game already exists.
+	For PS2 games on USB disks.
+	This is USB Advance format that is also used by OPL.
+	Use '-b' to do not update the 'ul.cfg' file.
+	Use '-i' to do set game-id manually.
+
+	>>> ul_list <<<
+	Alias: ull
+	Lists contents of 'ul.cfg' file in current directory on the disk.
+	Use '-l' switch to show more info (game-id).
+
+	>>> ul_dele <<<
+	Alias: uld
+	Delete entry from 'ul.cfg' file in current directory on the disk.
+	Specify one or more entries as asterissk with number, 1-based.
+	Eg. 'ul_dele *2' or 'ul_dele *1 *5 *10'
+	Use '-t' switch for test mode - don't delete or modify any files.
+
