+= 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@@.
