 == DIRECTORY BASED PROFILES ==
-If you want certain settings to be active in certain directories (and
-automatically switch back and forth between them), this is what you want.
+
+If you need to perform certain actions each time you enter certain
+directory-trees, this is the feature you are looking for.
+
+
+=== Initialisation ===
+To initialise the system, you need to call the function `chpwd_profiles' at
+some point in your `zshrc.local'; preferably **after** you configured the
+system. The configuration of the system is described further below.
+
+If you need to do initialisations the first time `chpwd_profiles' is called
+(which should be in your configuration file), you can do that in a function
+called "chpwd_profiles_init". That function needs to be defined **before**
+`chpwd_profiles' is called for this to work.
+
+During the **first** call of `chpwd_profiles' (and therefore all its profile
+functions) the parameter `$CHPWD_PROFILES_INIT' exists and is set to `1'. In
+all other cases, the parameter does not exist at all.
+
+
+=== Styles and Profile-names ===
+To store its configuration, the system uses **functions** and **styles**
+(zsh's context sensitive configuration system), such as this:
+
 \
 ```
 zstyle ':chpwd:profiles:/usr/src/grml(|/|/*)'   profile grml
 zstyle ':chpwd:profiles:/usr/src/debian(|/|/*)' profile debian
 ```
 
-When that's done and you enter a directory that matches the pattern
-in the third part of the context, a function called chpwd_profile_grml,
-for example, is called (if it exists).
+When that's done and you enter a directory that matches the pattern in the
+third part of the context, a function called chpwd_profile_grml, for example,

-set to 'default', which means chpwd_profile_default is attempted to
-be called.
+If no pattern matches (read: no profile is detected) the profile is set to
+'default', which means chpwd_profile_default is attempted to be called.
 
-A word about the context (the ':chpwd:profiles:*' stuff in the zstyle

-**$PWD**. That's why using a pattern such as /foo/bar(|/|/*) makes sense.

+
+=== Controlling Profile Execution ===
 
-Then there is the parameter **$CHPWD_PROFILE** which is set to the profile,
-that was active up to now. That way you can avoid running code for a
-profile that is already active, by running code such as the following
-at the start of your function:

+active, by running code such as the following at the start of your function:
 \
 ```
 function chpwd_profile_grml() {
     [[ ${profile} == ${CHPWD_PROFILE} ]] && return 1
-    ...
+  ...
 }
 ```
 
-The initial value for **$CHPWD_PROFILE** is 'default'.
+If you know you are going to do that all the time for each and every
+directory-profile function you are ever going to write, you may also set the
+`re-execute' style to `false' (which only defaults to `true' for backwards
+compatibility), like this:
+\
+```
+  zstyle ':chpwd:profiles:*' re-execute false

 == PROMPT ==
 
+The //grmlzshrc// now supplies three prompt themes compatible with zsh's
+**promptinit** system. The three themes are called **grml**, **grml-large** and
+**grml-chroot**.
+
+By default, **grml** is used, unless //$GRMLPROMPT// is set to a value larger
+than zero, in which case **grml-large** is used. Lastly, if //$GRML_CHROOT// is
+non-empty, **grml-chroot** is used.
+
+As usual, with promtinit themes, the user may switch to a different theme using
+the //prompt// utility:
+\
+```
+    prompt grml-large
+```
+
+That will use the **grml-large** prompt theme.
+
+The themes are highly customisable. The main source of documentation about
+customisation is the main **grml** theme's doc-string, that is available via
+the following command:
+\
+```
+    prompt -h grml
+```
+
+The other themes also come with doc-strings, but the main theme's is the
+canonical reference about all of them.
+
+This feature requires version //4.3.7// of the shell. Older versions will use
+the classic grml prompt as a fallback.
+
+A note to people who like customisation: If you are **not** using a prompt
+theme for your customisation, but you're either statically setting $PS1 (or
+$PROMPT) or you're constructing one of those variables in zsh's \`precmd()'
+function, make sure you are turning the zsh's prompt theme system **off**
+before doing so. A correct example customisation could look like this:
+\
+```
+    # Turn the prompt system off:
+    prompt off
+    # Customise the prompt yourself:
+    PS1='%~ %# '
+```
+
+You also add your own tokens by using the \`grml_theme_add_token()' function.

+//grmlzshrc// sets some environment variables, which influence the
+behaviour of applications.
+
+: **COLORTERM**
+Set to "yes". Some applications read this to learn about properties
+of the terminal they are running in.
+
+: **EDITOR**
+If not already set, sets the default editor. Falls back to vi(1),
+if vim(1) is not available.
+
+: **LESS_TERMCAP_***
+Some environment variables that add colour support to less(1) for viewing
+man pages. See termcap(5) for details.
+
+: **MAIL**
+The mailbox file for the current user is set to /var/mail/$USER, if not
+already set otherwise.
+
+: **PAGER**
+Set less(1) as default pager, if not already set to something different.
+
+: **SHELL**
+Set explicitly to /bin/zsh, to prevent certain terminal emulators to
+default to /bin/sh or /bin/bash.
+
+
+== OPTIONS ==
+Apart from zsh's default options, //grmlzshrc// sets some options
+that change the behaviour of zsh. Options that change Z-shell's default
+settings are marked by <grml>. But note, that zsh's defaults vary depending
+on its emulation mode (csh, ksh, sh, or zsh). For details, see zshoptions(1).
+
+: **append_history**
+Zsh sessions, that use //grmlzshrc//, will append their history list to the
+history file, rather than replace it. Thus, multiple parallel zsh sessions
+will all have the new entries from their history lists added to the history
+file, in the order that they exit. The file will still be periodically
+re-written to trim it when the number of lines grows 20% beyond the value
+specified by $SAVEHIST.
+
+: **auto_cd** <grml>
+If a command is issued that can't be executed as a normal command, and the
+command is the name of a directory, perform the cd command to that directory.
+
+: **auto_pushd** <grml>
+Make cd push the old directory onto the directory stack.
+
+: **completeinword** <grml>
+If the cursor is inside a word, completion is done from both ends;
+instead of moving the cursor to the end of the word first and starting
+from there.
+
+: **extended_glob** <grml>
+Treat the '#', '~' and '^' characters as active globbing pattern characters.
+
+: **extended_history** <grml>
+Save each command's beginning timestamp (in seconds since the epoch) and the
+duration (in seconds) to the history file.
+
+: **hash_list_all**
+Whenever a command completion is attempted, make sure the entire command
+path is hashed first. This makes the first completion slower.
+
+: **histignorealldups** <grml>
+If a new command line being added to the history list duplicates an
+older one, the older command is removed from the list, even if it is
+not the previous event.
+
+: **histignorespace** <grml>
+Remove command lines from the history list when the first character on
+the line is a space, or when one of the expanded aliases contains a
+leading space. Note that the command lingers in the internal history
+until the next command is entered before it vanishes.
+
+: **longlistjobs** <grml>
+List jobs in long format by default.
+
+: **nobeep** <grml>
+Avoid to beep on errors in zsh command line editing (zle).
+
+: **noglobdots**
+A wildcard character never matches a leading '.'.
+
+: **nohup** <grml>
+Do not send the hangup signal (HUP:1) to running jobs when the shell exits.
+
+: **nonomatch** <grml>
+If a pattern for filename generation has no matches, do not print an error
+and leave it unchanged in the argument list. This also applies to file
+expansion of an initial `~' or `='.
+
+: **notify**
+Report the status of background jobs immediately, rather than waiting until
+just before printing a prompt.
+
+: **pushd_ignore_dups** <grml>
+Don't push multiple copies of the same directory onto the directory stack.
+
+: **share_history** <grml>
+As each line is added to the history file, it is checked to see if anything
+else was written out by another shell, and if so it is included in the
+history of the current shell too. Using !-style history, the commands from
+the other sessions will not appear in the history list unless you explicitly
+type the "history" command. This option is activated for zsh versions >= 4,
+only.

+
+=== Customisation ===
+
+To customise keybindings, you can just use zsh's bindkey utility. However, if
+you plan to to use the `//zle-line-init//' or `//zle-line-finish//' hooks
+yourself, make sure you call the following functions in the respective hook:
+
+- **zle-line-init**: //zle-smkx//
+- **zle-line-finish**: //zle-rmkx//
+
+
+This is **required** so the keybindings set up by //grmlzshrc// work. The
+reason for this is to turn the terminal into the right mode while zsh's line
+editor (zle) is running. This enables us to query //terminfo// about escape
+sequences for special keys and thus simplify and generalise our keybinding
+section.

 //grmlzshrc// comes with a wide array of predefined aliases to ease the user's
-life.

-: **cmplayer** (//mplayer -vo fbdev//)
-Video player with framebuffer as video output device, so you can watch
-videos on a virtual tty. Hint: Using fbdev2 allows you to use the shell
-while watching a movie.
+life. A few aliases (like those involving //grep// or //ls//) use the option
+//--color=auto// for colourizing output. That option is part of **GNU**
+implementations of these tools, and will only be used if such an implementation
+is detected.
+
+: **acp** (//apt-cache policy//)
+With no arguments prints out the priorities of each source. If a package name
+is given, it displays detailed information about the priority selection of the
+package.
+
+: **acs** (//apt-cache search//)
+Searches debian package lists for the regular expression provided as argument.
+The search includes package names and descriptions. Prints out name and short
+description of matching packages.
+
+: **acsh** (//apt-cache show//)
+Shows the package records for the packages provided as arguments.
+
+: **adg** (//apt-get dist-upgrade//)
+Performs an upgrade of all installed packages. Also tries to automatically
+handle changing dependencies with new versions of packages. As this may change
+the install status of (or even remove) installed packages, it is potentially
+dangerous to use dist-upgrade; invoked by sudo, if necessary.
+
+: **ag** (//apt-get upgrade//)
+Downloads and installs the newest versions of all packages currently installed
+on the system. Under no circumstances are currently installed packages removed,
+or packages not already installed retrieved and installed. New versions of
+currently installed packages that cannot be upgraded without changing the install
+status of another package will be left at their current version. An update must
+be performed first (see au below); run by sudo, if necessary.
+
+: **agi** (//apt-get install//)
+Downloads and installs or upgrades the packages given on the command line.
+If a hyphen is appended to the package name, the identified package will be
+removed if it is installed. Similarly a plus sign can be used to designate a
+package to install. This may be useful to override decisions made by apt-get's
+conflict resolution system.
+A specific version of a package can be selected for installation by following
+the package name with an equals and the version of the package to select. This
+will cause that version to be located and selected for install. Alternatively a
+specific distribution can be selected by following the package name with a slash
+and the version of the distribution or the Archive name (stable, testing, unstable).
+Gets invoked by sudo, if user id is not 0.
+
+: **ati** (//aptitude install//)
+Aptitude is a terminal-based package manager with a command line mode similar to
+apt-get (see agi above); invoked by sudo, if necessary.
+
+: **au** (//apt-get update//)
+Resynchronizes the package index files from their sources. The indexes of
+available packages are fetched from the location(s) specified in
+/etc/apt/sources.list. An update should always be performed before an
+upgrade or dist-upgrade; run by sudo, if necessary.

+= ZSH REFCARD TAGS =
+If you read //grmlzshrc//'s code you may notice strange looking comments in
+it. These are there for a purpose. grml's zsh-refcard is automatically
+generated from the contents of the actual configuration file. However, we need
+a little extra information on which comments and what lines of code to take
+into account (and for what purpose).
+
+Here is what they mean:
+
+List of tags (comment types) used:
+: **#a#**
+Next line contains an important alias, that should be included in the
+grml-zsh-refcard. (placement tag: @@INSERT-aliases@@)
+
+: **#f#**
+Next line contains the beginning of an important function. (placement
+tag: @@INSERT-functions@@)
+
+: **#v#**
+Next line contains an important variable. (placement tag:
+@@INSERT-variables@@)
+
+: **#k#**
+Next line contains an important keybinding. (placement tag:
+@@INSERT-keybindings@@)
+
+: **#d#**
+Hashed directories list generation: //start//: denotes the start of a list of
+'hash -d' definitions. //end//: denotes its end. (placement tag:
+@@INSERT-hasheddirs@@)
+
+: **#A#**
+Abbreviation expansion list generation: //start//: denotes the beginning of
+abbreviations. //end//: denotes their end.
+\
+Lines within this section that end in '#d .*' provide extra documentation to
+be included in the refcard. (placement tag: @@INSERT-abbrev@@)
+
+: **#m#**
+This tag allows you to manually generate refcard entries for code lines that
+are hard/impossible to parse.
+Example:
+\
+```
+#m# k ESC-h Call the run-help function
+```
+\
+That would add a refcard entry in the keybindings table for 'ESC-h' with the
+given comment.
+\
+So the syntax is: #m# <section> <argument> <comment>
+
+: **#o#**
+This tag lets you insert entries to the 'other' hash. Generally, this should
+not be used. It is there for things that cannot be done easily in another way.
+(placement tag: @@INSERT-other-foobar@@)
+
+
+All of these tags (except for m and o) take two arguments, the first
+within the tag, the other after the tag:
+
+#<tag><section># <comment>
+
+Where <section> is really just a number, which are defined by the @secmap
+array on top of 'genrefcard.pl'. The reason for numbers instead of names is,
+that for the reader, the tag should not differ much from a regular comment.
+For zsh, it is a regular comment indeed. The numbers have got the following
+meanings:
+
+: **0**
+//default//
+
+: **1**
+//system//
+
+: **2**
+//user//
+
+: **3**
+//debian//
+
+: **4**
+//search//
+
+: **5**
+//shortcuts//
+
+: **6**
+//services//
+
+
+So, the following will add an entry to the 'functions' table in the 'system'
+section, with a (hopefully) descriptive comment:
+\
+```
+#f1# Edit an alias via zle
+edalias() {
+```
+\
+It will then show up in the @@INSERT-aliases-system@@ replacement tag that can
+be found in 'grml-zsh-refcard.tex.in'. If the section number is omitted, the
+'default' section is assumed. Furthermore, in 'grml-zsh-refcard.tex.in'
+@@INSERT-aliases@@ is exactly the same as @@INSERT-aliases-default@@. If you
+want a list of **all** aliases, for example, use @@INSERT-aliases-all@@.
