                      Instructions to RFC Authors

Status of this Memo

   This RFC specifies a standard for the Internet community.  Authors of
   RFCs are expected to adopt and implement this standard.  Distribution
   of this memo is unlimited.

1.  Introduction

   RFCs are distributed online by being stored as public access files,
   and a short message is sent to the distribution list indicating the
   availability of the memo.

   The online files are copied by the interested people and printed or
   displayed at their site on their equipment.  (An RFC may also be
   returned via email in response to an email query.)  This means that
   the format of the online files must meet the constraints of a wide
   variety of printing and display equipment.

2.  Format Rules

   To meet the distribution constraints the following rules are
   established for the two allowed formats for RFCs:  ASCII and

   The RFC Editor attempts to ensure a consistent RFC style.  To do this
   the RFC Editor may choose reformat the RFC submitted.  It is much
   easier to do this if the submission matches the style of the most
   recent RFCs.  Please do look at some recent RFCs and prepare yours in
   the same style.

   You must submit an editable online document to the RFC Editor.  The
   RFC Editor may require minor changes in format or style and will
   insert the actual RFC number.

   2a.  ASCII Format Rules:

      The character codes are ASCII.

      Each page must be limited to 58 lines followed by a form feed on a

RFC 1111                    RFC Instructions                 August 1989

      line by itself.

      Each line must be limited to 72 characters followed by carriage
      return and line feed.

      No overstriking (or underlining) is allowed.

      These "height" and "width" constraints include any headers,
      footers, page numbers, or left side indenting.

      Do not fill the text with extra spaces to provide a straight right

      Do not do hyphenation of words at the right margin.

      Do not use footnotes.  If such notes are necessary, put them at
      the end of a section, or at the end of the document.

      Use single spaced text within a paragraph, and one blank line
      between paragraphs.

      RFCs in ASCII Format may be submitted to the RFC Editor in email
      messages (or as online files) in either the finished publication
      format or in NROFF.  If you plan to submit a document in NROFF,
      please consult the RFC Editor first.

   2b.  PostScript Format Rules

   Standard page size is 8 1/2 by 11 inches.

      Margin of 1 inch on all sides (top, bottom, left, and right).

      Main text should have a point size of no less than 10 points with
      a line spacing of 12 points.

      Footnotes and graph notations no smaller than 8 points with a line
      spacing of 9.6 points.

      Three fonts are acceptable: Helvetica, Times Roman and Courier
      Plus their bold-face and italic versions.  These are the three
      standard fonts on most PostScript printers.

      Prepare diagrams and images based on lowest common denominator
      PostScript.  Consider common PostScript printer functionality and
      memory requirements.

      The following PostScript commands should not be used:
      initgraphics, erasepage, copypage, grestoreall, initmatrix,

RFC 1111                    RFC Instructions                 August 1989

      initclip, banddevice, framedevice, nulldevice and renderbands.

      These PostScript rules are likely to changed and expanded as
      experience is gained.

      RFCs in PostScript Format may be submitted to the RFC Editor in
      email messages (or as online files).  Since PostScript is not
      editable, an editable source version of the document must also be
      submitted.  If you plan to submit a document in PostScript, please
      consult the RFC Editor first.

3.  Status Statement

   Each RFC must include on its first page the "Status of this Memo"
   section which contains a paragraph describing the intention of the
   RFC.  This section is meant to convey the status granted by the RFC
   Editor and the Internet Activities Board (IAB).  There are several
   reasons for publishing a memo as an RFC, for example, to make
   available some information for interested people, or to begin or
   continue a discussion of an interesting idea, or to make available
   the specification of a protocol.

      The following sample paragraphs may be used to satisfy this
