#	Used in Perforce file patterns to indicate an absolute revision number.
*	A wildcard used in Perforce file patterns to match files at the current path level.
...	A wildcard used in Perforce file patterns to match files at the current path level and all levels below it.
@	Used in Perforce file patterns to indicate a symbolic revision identifier.
absolute revision	A revision number that identifies the ordinal version of a file. For example, foo.html#17 is the 17th version of foo.html.
branch	To create new files with the integrate command.
branch spec	A stored branch view.
branch view	A mapping between two depot files or paths that defines their branching relationship. Branch views control how the integrate command behaves when it is used to create new files, or to propagate changes between files. (Sometimes also called a "branch spec." See above.)
changelist	A record of a set of files changed at the same time.
client	The Perforce database entity that tracks your workspace and the files synced to it.
client spec	The specification of your workspace location, the depot files you plan on working with, and where they will appear in your workspace.
client view	The subset of depot files you plan on working with in your client workspace.
client workspace	The area on your local filesystem where you work on files managed by Perforce.
depot	A location in the master repository of files stored by the Perforce server.
file pattern	The Perforce syntax for specifying a file or set files. May include wildcards and/or revision specifiers.
filelog	The complete history of a file.
head revision	The latest or "tip" revision of a file.
job	A Perforce database object that can be used to track defects, enhancements, or other intended work.
label	Provides a means for marking a particular set of file revisions for later access. At any subsequent time, the label can be used to copy old file revisions into a client workspace.
label spec	The specification that defines a label name and a label view. The label spec creates the structure to build the label.
label view	The label view determines the depot files or paths that can be associated with a particular label.
labelsync	Performing a labelsync populates a label with files.
metadata	The data in a Perforce system that describes workspaces, file histories, users, changelists, etc.
opened files	The files you are changing (editing, adding, deleting, etc.) in your workspace.
path	A directory or folder.
pending changelist	A list of some or all of files open in your workspace.
port	The hostname and listen address that identifies the Perforce server (for example, public.perforce.com:1666).
review daemon	An optional program that the Perforce administrator can install to email users when changelists are submitted by other users.
standard (as in "Standard mode")	An instance of P4Web that can be used for workspace operations such as opening files and submitting changlists (as opposed to viewer mode). See Administering P4Web for details.
submit	The command that sends a pending changelist and contents of changed files to the depot.
submitted changelist	A permanent record that is created when a pending changelist is submitted.
symbolic revision	A revision symbol that identifies a file at a particular revision associated the state of the depot. For example: foo.html@1234 is the latest revision of foo.html at the moment changelist 1234 was submitted, regardless of whether foo.html was part of changelist 1234. foo.html@2000/06/06 is the latest revision of foo.html as of 00:00:00 hours, 06 June 2000. foo.html@topaz is the revision of foo.html currently in either the "topaz" client workspace or in the "topaz" label. (Because labels and clients can't have the same names, this situation is not ambigous.)
sync	The command that copies files from the depot to your workspace. (Short for "synchronize.")
user	The unique identifier of a Perforce user. (Usually the same as your login name.)
user spec	The specification describing various information associated with you as a Perforce user, such as your full name and your email address.
viewer (as in Viewer mode)	An instance of P4Web that can be used only for browsing, and cannot perform workspace operations.
wildcard	Perforce uses three wildcards for pattern matching: " * ", " ... ", and "%d". Any number and combination of these can be used in a single string: * matches anything except slashes; matches only within a single directory. ... matches anything including slashes; matches across multiple directories. %d is used for parametric substitution in views. Matches strings similarly to the * wildcard, but can be used to rearrange the order of the matched substrings.
workspace	The area on your local filesystem where you work on files managed by Perforce. (Also called a "client workspace.")
