# Doxyfile 1.5.3

# This file describes the settings to be used by the documentation system
# doxygen (www.doxygen.org) for a project
#
# All text after a hash (#) is considered a comment and will be ignored
# The format is:
#       TAG = value [value, ...]
# For lists items can also be appended using:
#       TAG += value [value, ...]
# Values that contain spaces should be placed between quotes (" ")

#---------------------------------------------------------------------------
# Project related configuration options
#---------------------------------------------------------------------------

# This tag specifies the encoding used for all characters in the config file that 
# follow. The default is UTF-8 which is also the encoding used for all text before 
# the first occurrence of this tag. Doxygen uses libiconv (or the iconv built into 
# libc) for the transcoding. See http://www.gnu.org/software/libiconv for the list of 
# possible encodings.

DOXYFILE_ENCODING      = UTF-8

# The PROJECT_NAME tag is a single word (or a sequence of words surrounded 
# by quotes) that should identify the project.

PROJECT_NAME           = @PACKAGE@

# The PROJECT_NUMBER tag can be used to enter a project or revision number. 
# This could be handy for archiving the generated documentation or 
# if some version control system is used.

PROJECT_NUMBER         = @VERSION@

# The OUTPUT_DIRECTORY tag is used to specify the (relative or absolute) 
# base path where the generated documentation will be put. 
# If a relative path is entered, it will be relative to the location 
# where doxygen was started. If left blank the current directory will be used.

OUTPUT_DIRECTORY       = doc

# If the CREATE_SUBDIRS tag is set to YES, then doxygen will create 
# 4096 sub-directories (in 2 levels) under the output directory of each output 
# format and will distribute the generated files over these directories. 
# Enabling this option can be useful when feeding doxygen a huge amount of 
# source files, where putting all generated files in the same directory would 
# otherwise cause performance problems for the file system.

CREATE_SUBDIRS         = NO

# The OUTPUT_LANGUAGE tag is used to specify the language in which all 
# documentation generated by doxygen is written. Doxygen will use this 
# information to generate all constant output in the proper language. 
# The default language is English, other supported languages are: 
# Afrikaans, Arabic, Brazilian, Catalan, Chinese, Chinese-Traditional, 
# Croatian, Czech, Danish, Dutch, Finnish, French, German, Greek, Hungarian, 
# Italian, Japanese, Japanese-en (Japanese with English messages), Korean,

# If the REPEAT_BRIEF tag is set to YES (the default) Doxygen will prepend

# brief descriptions will be completely suppressed.

REPEAT_BRIEF           = YES

# This tag implements a quasi-intelligent brief description abbreviator 
# that is used to form the text in various listings. Each string 
# in this list, if found as the leading text of the brief description, will be 
# stripped from the text and the result after processing the whole list, is 
# used as the annotated text. Otherwise, the brief description is used as-is. 
# If left blank, the following values are used ("$name" is automatically 
# replaced with the name of the entity): "The $name class" "The $name widget"

FULL_PATH_NAMES        = NO

# If the FULL_PATH_NAMES tag is set to YES then the STRIP_FROM_PATH tag 
# can be used to strip a user-defined part of the path. Stripping is 
# only done if one of the specified strings matches the left-hand part of

# If left blank the directory from which doxygen is run is used as the 
# path to strip.

STRIP_FROM_PATH        = 

# The STRIP_FROM_INC_PATH tag can be used to strip a user-defined part of 
# the path mentioned in the documentation of a class, which tells 
# the reader which header file to include in order to use a class.

# definition is used. Otherwise one should specify the include paths that 
# are normally passed to the compiler using the -I flag.

# If the JAVADOC_AUTOBRIEF tag is set to YES then Doxygen

MULTILINE_CPP_IS_BRIEF = NO

# If the DETAILS_AT_TOP tag is set to YES then Doxygen

# For example adding "sideeffect=\par Side Effects:\n" will allow you to
