-
-DESCRIPTION
-       Tracks your most used directories, based on 'frecency'.

-       -t     match by recent access only
-
-       -x     remove the current directory from the datafile
-
-EXAMPLES
-       z foo         cd to most frecent dir matching foo
-
-       z foo bar     cd to most frecent dir matching foo and bar
-
-       z -r foo      cd to highest ranked dir matching foo
-
-       z -t foo      cd to most recently accessed dir matching foo

-NOTES
-   Installation:
-       Put something like this in your $HOME/.bashrc or $HOME/.zshrc:
-
-              . /path/to/z.sh
-
-       cd around for a while to build up the db.
-
-       PROFIT!!
-
-       Optionally:
-              Set $_Z_CMD to change the command name (default z).
-              Set $_Z_DATA to change the datafile (default $HOME/.z).
-              Set $_Z_NO_RESOLVE_SYMLINKS to prevent symlink resolution.
-              Set $_Z_NO_PROMPT_COMMAND to handle PROMPT_COMMAND/precmd  your-
-              self.
-              Set $_Z_EXCLUDE_DIRS to an array of directories to exclude.
-              (These  settings  should  go  in .bashrc/.zshrc before the lines
-              added above.)
-              Install   the   provided   man   page   z.1    somewhere    like
-              /usr/local/man/man1.
-
-   Aging:
-       The rank of directories maintained by z undergoes aging based on a sim-
-       ple formula. The rank of each entry is incremented  every  time  it  is
-       accessed.  When  the  sum  of ranks is greater than 6000, all ranks are
-       multiplied by 0.99. Entries with a rank lower than 1 are forgotten.
-
-   Frecency:
-       Frecency is a portmanteau of 'recent' and 'frequency'. It is a weighted
-       rank  that depends on how often and how recently something occurred. As
-       far as I know, Mozilla came up with the term.
-
-       To z, a directory that has low ranking but has been  accessed  recently
-       will  quickly  have  higher rank than a directory accessed frequently a
-       long time ago.
-
-       Frecency is determined at runtime.
-
-   Common:
-       When multiple directories match all queries, and they all have a common
-       prefix, z will cd to the shortest matching directory, without regard to
-       priority.  This has been in effect, if  undocumented,  for  quite  some
-       time, but should probably be configurable or reconsidered.
-
-   Tab Completion:
-       z  supports tab completion. After any number of arguments, press TAB to
-       complete on directories that match each argument. Due to limitations of
-       the  completion  implementations,  only  the last argument will be com-
-       pleted in the shell.
-
-       Internally, z decides you've requested a completion if the  last  argu-
-       ment  passed  is  an  absolute  path to an existing directory. This may
-       cause unexpected behavior if the last argument to z begins with /.
-
-ENVIRONMENT
-       A function _z() is defined.
-
-       The contents of the variable $_Z_CMD is aliased to _z 2>&1. If not set,
-       $_Z_CMD defaults to z.
-
-       The  environment  variable $_Z_DATA can be used to control the datafile
-       location. If it is not defined, the location defaults to $HOME/.z.
-
-       The environment variable $_Z_NO_RESOLVE_SYMLINKS can be set to  prevent
-       resolving  of  symlinks.  If  it  is  not  set,  symbolic links will be
-       resolved when added to the datafile.
-
-       In bash, z appends a command to the PROMPT_COMMAND environment variable
-       to maintain its database. In zsh, z appends a function _z_precmd to the
-       precmd_functions array.
-
-       The environment variable $_Z_NO_PROMPT_COMMAND can be set if  you  want
-       to handle PROMPT_COMMAND or precmd yourself.
-
-       The  environment  variable  $_Z_EXCLUDE_DIRS  can be set to an array of
-       directories to exclude from tracking. $HOME is always excluded.  Direc-
-       tories must be full paths without trailing slashes.
-
-FILES
-       Data  is  stored  in  $HOME/.z.  This  can be overridden by setting the
-       $_Z_DATA environment variable. When initialized, z will raise an  error
-       if this path is a directory, and not function correctly.
-
-       A man page (z.1) is provided.
