#
# Note:   The  format  has  changed  slightly  (again).  The { ...  }
# syntax does now mean case-sensitive comparing, while [ ...  ] means
# case-insensitive   comparing  of  the  keywords.   Case-insensitive
# comparing  of  the  keywords  is  only  supported  on  a few of the
# keywords  (it's not meaningful in all contexts, and it slows ChkTeX
# down).  Keywords supporting this are marked throughout the file.
#
# You  may  also reset a list by saying "KEYWORD = { ...  }"; it will
# then be set equal to the contents of the list you specify.
#
# Comments  begin  with  `#', and continues for the rest of the line.
# Blank lines plus leading and trailing spaces are of course ignored.
#
# The general format of this file is the following:
#
# KEYWORD { item item ...} [ item item ... ] /* Adds items */
#
# KEYWORD [ item item ...] { item item ... } /* Adds items */
#
# KEYWORD = item
#
# KEYWORD = { item item ... } /* Clears list before adding */
#
# KEYWORD = [ item item ... ] /* Clears list before adding */
#
# This  does  _not_  mean  that  you may alternate the forms; certain
# keywords  demands  a  list, other a single value.  You thus have to
# look at the examples of their use.
#
# Please  also  note  that if you specify a list-keyword twice, we'll
# concatenate the lists.   If you specify a item-keyword twice, we'll
# kill the previous value.
#
# We  are  slightly  context-sensitive when detecting tokens like "}"
# and "]"; they have to be preceded by a space.  This generally makes
# life easier.
#
# Items  are separated by spaces.  Newlines are considered as spaces,
# but  can't be escaped.  You may surround items with quotes (`"') to
# easily put spaces into them.
#
# Escape sequences available:
#
#   Sequence        Resulting character
#   !               A space (type `! ', not just a exclamation mark)
#   !"              "
#   !#              #
#   !!              !
#   !{              {
#   !}              }
#   ![              [
#   !]              ]
#   !=              =
#   !b              Backspace
#   !n              New line
#   !r              Carriage return
#   !t              Tab
#   !f              Form feed
#   !xNN            NN must be a hexadecimal number (00 - ff),
#                   _both_ characters must be included.
#   !dNNN           DDD must be a decimal number (000 - 255), all
#                   three characters must be included. Unspecified
#                   results if DDD > 255.
#   !NNN            DDD must be a octal number (000 - 377), all
#                   three characters must be included. Unspecified
#                   results if DDD > 377.
#
# Minor  note:   As  you  can see, most of these escape sequences are
# equal  to  those  in  C  (with  some extensions); however, we use !
# instead of \ as escape character for obvious reasons.
#
#
# Quick summary of keywords follows.  Keywords marked with a * accept
# keywords accepting case-insensitive lists.

#                 processed  before  the ones you give on the command
#                 line.
#   HyphDash   \
#   NumDash     - Number of dashes allowed in different contexts.
#   WordDash   /
#   IJAccent    - Commands   which   puts   an  accent  _over_  their

#   ItalCmd     - Commands putting their argument into italic.
#   Linker      - Commands  which should have a non-breaking space in
#                 front.

#   MathRoman   - Mathematical   operators   with  LaTeX  replacement
#                 defined.
#   NoCharNext  - Insists on that certain commands aren't followed by
#                 certain characters.
#   NonItalic   - Commands immediately turning off italic mode.
#   NotPreSpaced- Commands  which should not have a space in front of
#                 them.

#   PostLink    - Commands which generates a page reference.
#   OutFormat   - Formats  to use for output.  See the -f & -v switch
#                 in the main doc.
#   QuoteStyle  - Either  "Traditional"  or "Logical".  See main doc,
#                 warning 38.
#   Silent      - These  commands  do not produce any textual output;
#                 and are thus allowed to have a space after them.
#   TabSize     - Tab size you are using.
#   TeXInputs   - Paths to search \input and \include files for.

# Here,  you  can  specify the length of various dashes.  We sort the
# dash according to which type of characters that are on the left and
# right of it.  We are only conclusive if they are the same.
#
# We associate as follows:
#
#     Name        Type of character on each side
#     HyphDash    Alphabetic (foo-bar)
#     NumDash     Numeric (2--3)
#     WordDash    Space (like this --- see?)
#
# Below you specify how many dashes which are legal in each case.  We
# define 0 as  a magic constant which always generates an error.  You
# may specify more than one legal dash-length.
#
# Let's look at an example.  You use the following dash-syntax:
#
#     foo-bar
#     2--3
#     like this---see?
#
#
# HYPHDASH { 1 3 }        # Either a hyphen, or inter-word
# NUMDASH { 2 }           # Between words
# WORDDASH { 0 }          # We never use this

# tell that Birch is one person and Swinnerton-Dyer is another.
