GLOSSARY

agg	Aggregate.
alg	Algorithm; typically a checksum algorithm.
blk	Block; a contiguous region of memory or data, typically of a standard
	size.
c	Child; as in an entry from a 'parent' directory.
chk	Checksum.
cmd	Command.
comp	Component.
conf	Configuration.
cud	Create, Update, Delete; a categorization of write operations.
d	Destination; typically the target 'dev' for a write operation.
desc	Description; relating to file metadata.  More specifically a
	description of an inode and its relevant metadata, including a checksum
	of the file content.  Metadata checksums are produced from these
	descriptions.
dev	Device; not a block device but a directory used internally by muxfs to
	store persistent data.  Muxfs mirrors data across an array of 'dev's.
dind	Device index; ranging from zero to the number of 'dev's minus one.
	Also used as the type for counting 'dev's.
dir	Directory.
ds	Dynamic stack.  Read ds.h for more information.
eno	An "external" inode number, exposed to through FUSE to the user via
	stat(2).  See also 'use_ino' in fuse_new(3).
ent	Entry; as in directory entry.
gen	Generate.  Read gen.c for more information.
ino	An "internal" inode number specific to one 'dev', hidden from the user.
inout	In-Out; a parameter to a function that is both an input and an output.
lfile	Large file; pertaining to files larger than MUXFS_BLOCK_SIZE, and their
	corresponding checksums.
lnk	Link; typically a symlink.
mnt(s)	Mount(s).
mp	Mount-point.
mt	Multi-threaded.
muxfs	The Multiplexed File System.
node	A file of any type.  This term is used to make clear that the "file" is
	not necessarily a regular file.  More generally an element of a tree
	structure.
off	Offset.
op(s)	Operation(s).
p	Parent; as in parent directory.  More generally a node "one step
	higher" in a tree structure.
rc	Return code; typically an int that is zero upon successful return from
	a function.
rd	Read.
reg	Regular file.
s	Source; typically the information source 'dev' of a restore operation.
sep	Separator; the '/' that separates files and directories in paths.
seq	Sequence number.
sz	Size; a number of bytes.
tx	Transfer.
ub	Upper bound.
unity	A unity build is a compilation technique whereby all modules are
	concatenated into a single module.  Unity builds provide the compiler
	with more information with which to optimize the program, and can
	increase the speed of compilation of individual programs from clean.
	By contrast an incremental build may compile a suite of programs faster
	if the programs share some of their modules.  Incremental builds tend
	to provide clearer debugging information, may compile faster when
	updating a previous incremental build, and tend to result in less
	optimized programs.
wr	Write.
