# The converter functions take a line as argument and return a list: 
# 	(Bool, NewLine), 
# where the Bool says if  we've modified anything and the NewLine is 
# the new line, if so, which will be used to replace the old line.

# Incremented to format 2, r39670 by jrioux
#   Support for multiple file extensions per format.
#   No conversion necessary.

# Incremented to format 3, r39705 by tommaso
#   Support for file formats that are natively (g)zipped.
#   We must add the flag zipped=native to formats that
#   were previously hardcoded in the C++ source: dia.

# Incremented to format 4, r40028 by vfr
#   Remove support for default paper size.

# Incremented to format 5, r40030 by vfr
#   Add a default length unit.
#   No conversion necessary.

#   Add mime type to file format

# Incremented to format 8, 288c1e0f by rgh
#   Add "nice" flag for converters
#   No conversion necessary.

# Incremented to format 9, a18af620 by spitz
#  Remove default_language rc.

# Incremented to format 10, 4985015 by tommaso
#  Add close_buffer_with_last_view in preferences.
#  No conversion necessary.

# Incremented to format 11, by gb
#   Split pdf format into pdf and pdf6

# Incremented to format 12, by vfr
#   Add option to use the system's theme icons
#   No conversion necessary.

# Incremented to format 13, by bh
#   Rename mac_like_word_movement to mac_like_cursor_movement

# Incremented to format 14, by spitz
#   New RC default_otf_view_format
#   No conversion necessary.

# Incremented to format 15, by prannoy
#   Add fullscreen_statusbar
#   No conversion necessary.

# Incremented to format 16, by lasgouttes
#  Remove force_paint_single_char rc.

# Incremented to format 18, by ef
#   Add option to allow saving the document directory
