Style file

The style file format is very simple. It is a list of <specifier, attribute> pairs. There are two types of specifiers (input and output). The pairs don't have to obey any particular order in the file. A line lead by `%' is a comment. The following is a list of all the specifiers and their respective arguments where <string> is an arbitrary string delimited by double quotes ("..."), <char> is a single letter embraced by single quotes ('...'), and <number> is a nonnegative integer. The maximum length of a <string> is 144. Notice that a backslash must be escaped (by an extra backslash) in the string quotation. Anything not specified in the style file will be assigned a default value, which is shown at the rightmost column. This file can reside anywhere in the path defined by the environment variable INDEXSTYLE.
