DESCRIPTION

       This  document  specifies both names and syntax of all the commands which together are the
       docidx markup language, version 1.  As this document is intended to  be  a  reference  the
       commands  are  listed in alphabetical order, and the descriptions are relatively short.  A
       beginner should read the much more informally written docidx language introduction first.

COMMANDS

       comment plaintext
              Index markup. The argument text is marked up as a comment standing outside  of  the
              actual text of the document. Main use is in free-form text.

       include filename
              Templating.  The  contents of the named file are interpreted as text written in the
              docidx markup and processed in the place of the include command. The markup in  the
              file has to be self-contained. It is not possible for a markup command to cross the
              file boundaries.

       index_begin text title
              Document structure. The command to start an index. The arguments are  a  label  for
              the  whole group of documents the index refers to (text) and the overall title text
              for the index (title), without markup.

              The label often is the name of the package (or extension) the documents belong to.

       index_end
              Document structure. Command to end an index. Anything in the document coming  after
              this command is in error.

       key text
              Index structure. This command adds the keyword text to the index.

       lb     Text.  The command is replaced with a left bracket. Use in free-form text. Required
              to avoid interpretation of a left bracket as the start of  a  markup  command.  Its
              usage is restricted to the arguments of other markup commands.

       manpage file text
              Index  structure.  This  command  adds  an  element  to the index which refers to a
              document. The document is specified  through  the  symbolic  name  file.  The  text
              argument is used to label the reference.

              Symbolic names are used to preserve the convertibility of this format to any output
              format. The actual name of the file will  be  inserted  by  the  chosen  formatting
              engine  when converting the input. This will be based on a mapping from symbolic to
              actual names given to the engine.

       rb     Text. The command is replaced with a right bracket. Use in free-form text. Required
              to  avoid  interpretation  of  a  right bracket as the end of a markup command. Its
              usage is restricted to the arguments of other commands.

       url url label
              Index structure. This is the second command to add an  element  to  the  index.  To
              refer  to  a  document  it  is  not  using a symbolic name however, but a (possibly
              format-specific) url describing the exact location of the document indexed here.

       vset varname value
              Templating. In this form the command  sets  the  named  document  variable  to  the
              specified  value.  It does not generate output. I.e. the command is replaced by the
              empty string.

       vset varname
              Templating. In this form the command is replaced by the value of the named document
              variable
