==== How to build ====

make test

Builds the targets for testing Layer 0 and Layer 1.
Required for Layer0Test and Layer1CombinedTest.

make main

Builds the target for testing Layer 2.  Includes TestMain

make fuse

Builds the target for running on FUSE.

==== How to run tests ====

./Layer0Test DISK_SIZE

Tests the Layer 0 disk emulator.  Makes a disk and attempts
some simple, predetermined writes on it.

DISK_SIZE is in bytes.

./Layer1CombinedTest MODE FS_NUM_DATA_BLOCKS FS_NUM_INODES

Tests the Layer 1 functionality by making a file system
and running a number of predetermined stress tests like
allocating every inode/data block and writing data.

MODE is either "i" or "d", "i" to test the inode functionality,
"d" to test the data block functionality.

FS_NUM_DATA_BLOCKS and FS_NUM_INODES determine the size of the
file system, with some minimum values.

./TestMain FS_NUM_DATA_BLOCKS FS_NUM_INODES

Tests the Layer 2 functionality by making a file system
with the parameters specified and giving a menu of 
commands.  Currently, mkdir, mknod, unlink, open, close, read, write
system calls are implemented and tested.

In addition to these syste calls, "quit" allows you to exit the program;
"stats" is a debugging function that will show you the state of the FS
after makefs or any command.

==== How to run on FUSE ====

1. Build the fuse target.
2. Make a directory that will be the root directory.
3. Run InitFS (the disk device path must be defined in Globals.h).
4. Run fuseDaemon -s ROOT_DIR_PATH
5. Enjoy!
