+# 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.

+#                 line.
+#   HyphDash   \
+#   NumDash     - Number of dashes allowed in different contexts.

+#   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.

+#   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.
