 .SH DESCRIPTION
 .PP
-These routines allows a C procedure to take a snapshot of the current
-state of an interpreter so that it can be restored after a call
-to \fBTcl_Eval\fR or some other routine that modifies the interpreter
-state.  There are two triplets of routines meant to work together.
+These routines save the state of an interpreter before a call to a routine such
+as \fBTcl_Eval\fR, and restore the state afterwards.
 .PP
-The first triplet stores the snapshot of interpreter state in
-an opaque token returned by \fBTcl_SaveInterpState\fR.  That token
-value may then be passed back to one of \fBTcl_RestoreInterpState\fR
-or \fBTcl_DiscardInterpState\fR, depending on whether the interp
-state is to be restored.  So long as one of the latter two routines
-is called, Tcl will take care of memory management.
+\fBTcl_SaveInterpState\fR saves the parts of \fIinterp\fR that comprise the
+result of a script, including the resulting value, the return code passed as
+\fIstatus\fR, and any options such as \fB\-errorinfo\fR and \fB\-errorcode\fR.
+It returns a token for the saved state.  The interpreter result is not reset
+and no interpreter state is changed.
 .PP
-The second triplet stores the snapshot of only the interpreter
-result (not its complete state) in memory allocated by the caller.
-These routines are passed a pointer to \fBTcl_SavedResult\fR
-that is used to store enough information to restore the interpreter result.
-\fBTcl_SavedResult\fR can be allocated on the stack of the calling
-procedure.  These routines do not save the state of any error
-information in the interpreter (e.g. the \fB\-errorcode\fR or
-\fB\-errorinfo\fR return options, when an error is in progress).
+\fBTcl_RestoreInterpState\fR restores the state indicated by \fIstate\fR and
+returns the \fIstatus\fR originally passed in the corresponding call to
+\fBTcl_SaveInterpState\fR.
 .PP
-Because the routines \fBTcl_SaveInterpState\fR,
-\fBTcl_RestoreInterpState\fR, and \fBTcl_DiscardInterpState\fR perform
-a superset of the functions provided by the other routines,
-any new code should only make use of the more powerful routines.
-The older, weaker routines \fBTcl_SaveResult\fR, \fBTcl_RestoreResult\fR,
-and \fBTcl_DiscardResult\fR continue to exist only for the sake
-of existing programs that may already be using them.
+If a saved state is not restored, \fBTcl_DiscardInterpState\fR must be called
+to release it.  A token used to discard or restore state must not be used
+again.
 .PP
-\fBTcl_SaveInterpState\fR takes a snapshot of those portions of
-interpreter state that make up the full result of script evaluation.
-This include the interpreter result, the return code (passed in
-as the \fIstatus\fR argument, and any return options, including
-\fB\-errorinfo\fR and \fB\-errorcode\fR when an error is in progress.
-This snapshot is returned as an opaque token of type \fBTcl_InterpState\fR.
-The call to \fBTcl_SaveInterpState\fR does not itself change the
-state of the interpreter.  Unlike \fBTcl_SaveResult\fR, it does
-not reset the interpreter.
+\fBTcl_SaveResult\fR, \fBTcl_RestoreResult\fR, and \fBTcl_DiscardResult\fR are
+deprecated.  Instead use \fBTcl_SaveInterpState\fR,
+\fBTcl_RestoreInterpState\fR, and \fBTcl_DiscardInterpState\fR, which are more
+capable.
 .PP
-\fBTcl_RestoreInterpState\fR accepts a \fBTcl_InterpState\fR token
-previously returned by \fBTcl_SaveInterpState\fR and restores the
-state of the interp to the state held in that snapshot.  The return
-value of \fBTcl_RestoreInterpState\fR is the status value originally
-passed to \fBTcl_SaveInterpState\fR when the snapshot token was
-created.
+\fBTcl_SaveResult\fR moves the result of \fIinterp\fR to the location
+\fIstatePtr\fR points to and returns the interpreter result to its initial
+state.  It does not save options such as \fB\-errorcode\fR or
+\fB\-errorinfo\fR.
 .PP
-\fBTcl_DiscardInterpState\fR is called to release a \fBTcl_InterpState\fR
-token previously returned by \fBTcl_SaveInterpState\fR when that
-snapshot is not to be restored to an interp.
-.PP
-The \fBTcl_InterpState\fR token returned by \fBTcl_SaveInterpState\fR
-must eventually be passed to either \fBTcl_RestoreInterpState\fR
-or \fBTcl_DiscardInterpState\fR to avoid a memory leak.  Once
-the \fBTcl_InterpState\fR token is passed to one of them, the
-token is no longer valid and should not be used anymore.
-.PP
-\fBTcl_SaveResult\fR moves the string and value results
-of \fIinterp\fR into the location specified by \fIstatePtr\fR.
-\fBTcl_SaveResult\fR clears the result for \fIinterp\fR and
-leaves the result in its normal empty initialized state.
-.PP
-\fBTcl_RestoreResult\fR moves the string and value results from
-\fIstatePtr\fR back into \fIinterp\fR.  Any result or error that was
-already in the interpreter will be cleared.  The \fIstatePtr\fR is left
-in an uninitialized state and cannot be used until another call to
+\fBTcl_RestoreResult\fR clears any existing result or error in \fIinterp\fR and
+moves the result from \fIstatePtr\fR back to \fIinterp\fR.  \fIstatePtr\fR is
+then in an undefined state and must not be used until passed again to
 \fBTcl_SaveResult\fR.
 .PP
-\fBTcl_DiscardResult\fR releases the saved interpreter state
-stored at \fBstatePtr\fR.  The state structure is left in an
-uninitialized state and cannot be used until another call to
+\fBTcl_DiscardResult\fR releases the state stored at \fBstatePtr\fR, which is
+then in an undefined state and must not be used until passed again to
 \fBTcl_SaveResult\fR.
 .PP
-Once \fBTcl_SaveResult\fR is called to save the interpreter
-result, either \fBTcl_RestoreResult\fR or
-\fBTcl_DiscardResult\fR must be called to properly clean up the
-memory associated with the saved state.
+If a saved result is not restored, \fBTcl_DiscardResult\fR must be called to
+release it.

+.SH DESCRIPTION
+Abstract classes are classes that can contain definitions, but which cannot be
+directly manufactured; they are intended to only ever be inherited from and
+instantiated indirectly. The characteristic methods of \fBoo::class\fR
+(\fBcreate\fR and \fBnew\fR) are not exported by an instance of
+\fBoo::abstract\fR.
+.PP
+Note that \fBoo::abstract\fR is not itself an instance of \fBoo::abstract\fR.
+.SS CONSTRUCTOR
+The \fBoo::abstract\fR class does not define an explicit constructor; this
+means that it is effectively the same as the constructor of the
+\fBoo::class\fR class.
+.SS DESTRUCTOR
+The \fBoo::abstract\fR class does not define an explicit destructor;
+destroying an instance of it is just like destroying an ordinary class (and
+will destroy all its subclasses).
+.SS "EXPORTED METHODS"
+The \fBoo::abstract\fR class defines no new exported methods.
+.SS "NON-EXPORTED METHODS"
+The \fBoo::abstract\fR class explicitly states that \fBcreate\fR,
+\fBcreateWithNamespace\fR, and \fBnew\fR are unexported.
+.SH EXAMPLES
+.PP
+This example defines a simple class hierarchy and creates a new instance of
+it. It then invokes a method of the object before destroying the hierarchy and
+showing that the destruction is transitive.

+object (as reported by \fBself\fR) when executed. Any additional arguments
+provided will be provided as leading arguments to the callback. The resulting
+script fragment shall be a proper list.

+Note that it is up to the caller to ensure that the current object is able to

+\fImethodName\fR may refer to any exported or unexported method, but may not

+The \fBclassvariable\fR command is available within methods. It takes a series
+of one or more variable names and makes them available in the method's scope;

+.fi
+.SH DESCRIPTION
+.PP
+The cookiejar package provides an implementation of the http package's cookie
+jar protocol using an SQLite database. It provides one main command,
+\fB::http::cookiejar\fR, which is a TclOO class that should be instantiated to
+create a cookie jar that manages a particular HTTP session.
+.PP
+The database management policy can be controlled at the package level by the
+\fBconfigure\fR method on the \fB::http::cookiejar\fR class object:
+.TP
+\fB::http::cookiejar configure\fR ?\fIoptionName\fR? ?\fIoptionValue\fR?
+.
+If neither \fIoptionName\fR nor \fIoptionValue\fR are supplied, this returns a
+copy of the configuration as a Tcl dictionary. If just \fIoptionName\fR is
+supplied, just the value of the named option is returned. If both
+\fIoptionName\fR and \fIoptionValue\fR are given, the named option is changed
+to be the given value.
+.RS
+.PP
+Supported options are:
+.TP
+\fB\-domainfile \fIfilename\fR
+.
+A file (defaulting to within the cookiejar package) with a description of the
+list of top-level domains (e.g., \fB.com\fR or \fB.co.jp\fR). Such domains
+\fImust not\fR accept cookies set upon them. Note that the list of such
+domains is both security-sensitive and \fInot\fR constant and should be
+periodically refetched. Cookie jars maintain their own cache of the domain
+list.
+.TP
+\fB\-domainlist \fIurl\fR
+.
+A URL to fetch the list of top-level domains (e.g., \fB.com\fR or
+\fB.co.jp\fR) from.  Such domains \fImust not\fR accept cookies set upon
+them. Note that the list of such domains is both security-sensitive and
+\fInot\fR constant and should be periodically refetched. Cookie jars maintain
+their own cache of the domain list.
+.TP
+\fB\-domainrefresh \fIintervalMilliseconds\fR
+.
+The number of milliseconds between checks of the \fI\-domainlist\fR for new
+domains.
+.TP
+\fB\-loglevel \fIlevel\fR
+.
+The logging level of this package. The logging level must be (in order of
+decreasing verbosity) one of \fBdebug\fR, \fBinfo\fR, \fBwarn\fR, or
+\fBerror\fR.
+.TP
+\fB\-offline \fIflag\fR
+.
+Allows the cookie managment engine to be placed into offline mode. In offline
+mode, the list of domains is read immediately from the file configured in the
+\fB\-domainfile\fR option, and the \fB\-domainlist\fR option is not used; it
+also makes the \fB\-domainrefresh\fR option be effectively ignored.
+.TP
+\fB\-purgeold \fIintervalMilliseconds\fR
+.
+The number of milliseconds between checks of the database for expired
+cookies; expired cookies are deleted.
+.TP
+\fB\-retain \fIcookieCount\fR
+.
+The maximum number of cookies to retain in the database.
+.TP
+\fB\-vacuumtrigger \fIdeletionCount\fR
+.
+A count of the number of persistent cookie deletions to go between vacuuming
+the database.
+.RE
+.PP
+Cookie jar instances may be made with any of the standard TclOO instance
+creation methods (\fBcreate\fR or \fBnew\fR).
+.TP
+\fB::http::cookiejar new\fR ?\fIfilename\fR?
+.
+If a \fIfilename\fR argument is provided, it is the name of a file containing
+an SQLite database that will contain the persistent cookies maintained by the
+cookie jar; the database will be created if the file does not already
+exist. If \fIfilename\fR is not supplied, the database will be held entirely within
+memory, which effectively forces all cookies within it to be session cookies.
+.SS "INSTANCE METHODS"
+.PP
+The following methods are supported on the instances:
+.TP
+\fIcookiejar\fR \fBdestroy\fR
+.
+This is the standard TclOO destruction method. It does \fInot\fR delete the
+SQLite database if it is written to disk. Callers are responsible for ensuring
+that the cookie jar is not in use by the http package at the time of
+destruction.
+.TP
+\fIcookiejar\fR \fBforceLoadDomainData\fR
+.
+This method causes the cookie jar to immediately load (and cache) the domain
+list data. The domain list will be loaded from the \fB\-domainlist\fR
+configured a the package level if that is enabled, and otherwise will be
+obtained from the \fB\-domainfile\fR configured at the package level.
+.TP
+\fIcookiejar\fR \fBgetCookies\fR \fIprotocol host path\fR
+.
+This method obtains the cookies for a particular HTTP request. \fIThis
+implements the http cookie jar protocol.\fR
+.TP
+\fIcookiejar\fR \fBpolicyAllow\fR \fIoperation domain path\fR
+.
+This method is called by the \fBstoreCookie\fR method to get a decision on
+whether to allow \fIoperation\fR to be performed for the \fIdomain\fR and
+\fIpath\fR. This is checked immediately before the database is updated but
+after the built-in security checks are done, and should return a boolean
+value; if the value is false, the operation is rejected and the database is
+not modified. The supported \fIoperation\fRs are:
+.RS
+.TP
+\fBdelete\fR
+.
+The \fIdomain\fR is seeking to delete a cookie.
+.TP
+\fBsession\fR
+.
+The \fIdomain\fR is seeking to create or update a session cookie.
+.TP
+\fBset\fR
+.
+The \fIdomain\fR is seeking to create or update a persistent cookie (with a
+defined lifetime).
+.PP
+The default implementation of this method just returns true, but subclasses of
+this class may impose their own rules.
+.RE
+.TP
+\fIcookiejar\fR \fBstoreCookie\fR \fIoptions\fR
+.
+This method stores a single cookie from a particular HTTP response. Cookies
+that fail security checks are ignored. \fIThis implements the http cookie jar
+protocol.\fR
+.TP
+\fIcookiejar\fR \fBlookup\fR ?\fIhost\fR? ?\fIkey\fR?
+.
+This method looks a cookie by exact host (or domain) matching. If neither
+\fIhost\fR nor \fIkey\fR are supplied, the list of hosts for which a cookie is
+stored is returned. If just \fIhost\fR (which may be a hostname or a domain
+name) is supplied, the list of cookie keys stored for that host is returned.
+If both \fIhost\fR and \fIkey\fR are supplied, the value for that key is
+returned; it is an error if no such host or key match exactly.
+.SH "EXAMPLES"
+.PP
+The simplest way of using a cookie jar is to just permanently configure it at
+the start of the application.
