./manipulator [-i]|[-f file1 file2] [-h]

	This program is a string and numbers manipulator and provides following fuctions:
		base1_2_base2 : Converts a number in base1 to appropriate representation in base2
		                Usage: base1_2_base2 base1 base2 number
		                       base1 = The source base between 2 and 16
		                       base2 = Destination base between 2 and 16
		                       number = The number in base1
		                Output: Prints the representation of the input number in base2
		hexadec_2_bit : Takes a hexadecimal number and checks which bits have been turned ON
		                Usage: hexadec_2_bit number
		                       number = A hexadecimal number as input
		                Output: Prints which all bits are switched on among the initial 10 bits
		                        Ignores all the bits after the 10th bit. Bits are numbered from right
		                Bit-Mapping: 1 1 1 1 1 1 1 1 1 1
		                             J I H G F E D C B A
		fibonacci_ser : Takes an number and prints the fibonacci series for that number using recursion
		                Usage: fibonacci_ser number
		                       number = An integer
		                Output: The comma seperated fibonacci series corresponding to the input number
		reverse_strng : Takes a string and prints that string in reverse order
		                Usage: reverse_string string
		                       string = Some string which can include special character and alphanumerics
		                Output: Prints the input string in reverse order
		remove_spaces : Takes a string and removes all extra whitespaces (space and TAB characters)
		                Usage: remove_spaces string
		                       string = Some string with extra whitespaces (space and TAB charcters) in it
		                Output: Prints the string back with all extra spaces removed
		character_frq : Takes a string and prints the character frequency for all the characters in it
		                Usage: character_frq string
		                       string = Some string
		                Output: A comma seperated list of character count in the given input string
		cipher_string : Takes a string and ciphers it by shifting and rotating characters
		                Usage: cipher_string shift_int rotate_int string
		                       shift_int: An integer between -9 and 9
		                                  A negative integer means shift left and positive means shift right
		                       rotate_int: An integer between -9 and 9
		                                   A negative integer means reverse rotation and a postivie means forward rotation
		                       string: Some input alphanumeric string
		                       Output: The ciphered string after shifting and rotations
		exit_program_ : Quits the program
		                Usage: exit_program_

	The command line arguments accepted for this program are as follows:
		-i            : To run the program interactively and read the input from stdin
		-f file1 file2: To read the program inputs from a file1 and output to file2.
		                Only one of -i or -f should be used. If both are present it gives preference to interactive mode
		-h            : To print this help
