Project details

	Required fuse version: FUSE 3
	Developed and tested on Linux (Arch/Manjaro distros)

	Build:
		make
	Run:
		./sifs -f [mount_folder-path] [tar-path]
		./sifs -f mountFolder testTar.tar
	FUSE Debug:
		./sifs -f -d [mount_folder-path] [tar-path]
	
	To build a new tar instead of testTar.tar use:
		tar -cvf TAR_NAME.tar ./FILE1 ./FILE2 
							  ^^ note the ./ before files	
		
	Currently working (and tested):
		* Mounting the tar archive to a folder
		* Building a tree from the tar structure using info provided by [sifs_getattr]
		* cd 			[sifs_opendir]
		* ls 			[sifs_readdir]
		* mkdir 		[sifs_mkdir]
		* touch 		[sifs_mknod]
		* Opening/Modifying (nano/vim) FILE [sifs_mknod] [sifs_open] [sifs_read] [sifs_write]
		
		
	Currently working but sometimes causing random bugs, generally hard to recreate:
		* rm FILE 	[sifs_unlink]
		* rm -r FOLDER [sifs_rmdir]
		* Saving changes in the same tar [sifs_destroy]
