+\fBTclzipfs_Init()\fR performs one-time initialization of the file system

+is provided and supplemental Tcl commands are created in the given
+interpreter \fIinterp\fR.

+\fBTclzipfs_SafeInit()\fR is the version of \fBTclzipfs_Init()\fR for

+If \fIzipname\fR is a NULL pointer, information on all currently mounted
+ZIP file systems is written into \fIinterp\fR's result as a sequence of
+mount points and ZIP file names.
+.PP
+\fBTclzipfs_Unmount()\fR undoes the effect of \fBTclzipfs_Mount()\fR,

+.SH DESCRIPTION
+.PP
+The \fBzipfs\fR package provides tcl with the ability to mount
+the contents of a zip file as a virtual file system.
+.TP
+\fBzipfs exists\fR \fIfilename\fR
+.
+Return 1 if the given filename exists in the mounted zipfs and 0 if it does not.
+.TP
+\fBzipfs find\fR \fIdir\fR
+.
+Recursively lists files including and below the directory \fIdir\fR.
+The result list consists of relative path names starting from the
+given directory. This command is also used by the \fBzipfs mkzip\fR
+and \fBzipfs mkimg\fR commands. 
+.TP
+\fBzipfs info\fR \fIfile\fR
+.
+Return information about the given file in the mounted zipfs.  The information
+consists of (1) the name of the ZIP archive file that contains the file,
+(2) the size of the file after decompressions, (3) the compressed size of
+the file, and (4) the offset of the compressed data in the ZIP archive file.
+.RS
+.PP
+Note: querying the mount point gives the start of zip data offset in (4),
+which can be used to truncate the zip info off an executable.
+.RE
+.TP
+\fBzipfs list\fR \fB?(-glob|-regexp)?\fR \fI?pattern?\fR
+.
+Return a list of all files in the mounted zipfs.  The order of the names
+in the list is arbitrary.
+.TP
+\fBzipfs mkimg\fR \fIoutfile\fR \fIindir\fR \fI?strip?\fR \fI?password?\fR \fI?infile?\fR
+.
+Creates an image (potentially a new executable file) similar to
+\fBzipfs mkzip\fR. If the \fIinfile\fR parameter is specified,
+this file is prepended in front of the ZIP archive, otherwise the file
+returned by \fBTcl_NameOfExecutable(3)\fR (i.e. the executable file of
+the running process) is used. If the \fIpassword\fR parameter is not empty,
+an obfuscated version of that password is placed between the image and ZIP
+chunks of the output file and the contents of the ZIP chunk are protected
+with that password.
+.RS
+.PP
+Caution: highly experimental, not usable on Android, only partially tested
+on Linux and Windows.
+.RE
+.TP
+\fBzipfs mkkey\fR \fIpassword\fR
+.
+For the clear text \fIpassword\fR argument an obfuscated string version
+is returned with the same format used in the \fBzipfs mkimg\fR command.
+.TP
+\fBzipfs mkzip\fR \fIoutfile\fR \fIindir\fR \fI?strip?\fR \fI?password?\fR
+.
+Creates a ZIP archive file named \fIoutfile\fR from the contents of the input
+directory \fIindir\fR (contained regular files only) with optional ZIP
+password \fIpassword\fR. While processing the files below \fIindir\fR the
+optional file name prefix given in \fIstrip\fR is stripped off the beginning
+of the respective file name.
+.RS
+.PP
+Caution: the choice of the \fIindir\fR parameter
+(less the optional stripped prefix) determines the later root name of the
+archive's content. 
+.RE
+.TP
+\fBzipfs mount ?\fIzipfile\fR? ?\fImountpoint\fR? ?\fIpassword\fR?
+.
+The \fBzipfs mount\fR command mounts a ZIP archive file as a VFS.
+After this command executes, files contained in \fIzipfile\fR
+will appear to Tcl to be regular files at the mount point.
+.RS
+.PP
+With no \fImountpoint\fR, returns the mount point for \fIzipfile\fR.
+With no \fIzipfile\fR, return all zipfile/mount point pairs.
+If \fImountpoint\fR is specified as an empty string, the mount point
+will be the current directory. If \fIpassword\fR is specified, files from
+\fIzipfile\fR are decrypted using this password when read.
+.RE
+.TP
+\fBzipfs unmount \fIzipfile\fR
+.
+Unmounts a previously mounted ZIP archive file \fIzipfile\fR.
