#
# Zsh-z maintains a jump-list of the directories you actually use.
#
# INSTALL:
# * put something like this in your .zshrc:
# source /path/to/zsh-z.plugin.zsh
# * cd around for a while to build up the database
#
# USAGE:
# * z foo cd to the most frecent directory matching foo
# * z foo bar cd to the most frecent directory matching both foo and bar
# (e.g. /foo/bat/bar/quux)
# * z -r foo cd to the highest ranked directory matching foo
# * z -t foo cd to most recently accessed directory matching foo
# * z -l foo List matches instead of changing directories
# * z -e foo Echo the best match without changing directories
# * z -c foo Restrict matches to subdirectories of PWD
# * z -x Remove a directory (default: PWD) from the database
# * z -xR Remove a directory (default: PWD) and its subdirectories from
# the database
#
# ENVIRONMENT VARIABLES:
#
# ZSHZ_CASE -> if `ignore', pattern matching is case-insensitive; if `smart',
# pattern matching is case-insensitive only when the pattern is all
# lowercase
# ZSHZ_CD -> the directory-changing command that is used (default: builtin cd)
# ZSHZ_CMD -> name of command (default: z)
# ZSHZ_COMPLETION -> completion method (default: 'frecent'; 'legacy' for
# alphabetic sorting)
# ZSHZ_DATA -> name of datafile (default: ~/.z)
# ZSHZ_EXCLUDE_DIRS -> array of directories to exclude from your database
# (default: empty)
# ZSHZ_KEEP_DIRS -> array of directories that should not be removed from the
# database, even if they are not currently available (default: empty)
# ZSHZ_MAX_SCORE -> maximum combined score the database entries can have
# before beginning to age (default: 9000)
# ZSHZ_NO_RESOLVE_SYMLINKS -> '1' prevents symlink resolution
# ZSHZ_OWNER -> your username (if you want use Zsh-z while using sudo -s)
# ZSHZ_UNCOMMON -> if 1, do not jump to "common directories," but rather drop
# subdirectories based on what the search string was (default: 0)
