# @brief This program converts supported tablature source files to a printable format
#
# @section description Description
# Creates Song objects of all tablatures it can find in a given directory or its subdirectories
# Supported inputs currently: Any .txt file, as long as each section has a corresponding [<sectionName>] delimiter
# Supported outputs currently: PNG format
# Song objects are then parsed into separate metadata information and sections
# Sections contain lines of lyric and corresponding tablature data
# The program then tries to fit these sections within the chosen output dimensions (currently A4)
#   as best as it can, shrinking or growing sections to fit the remaining space
#
# @section notes Notes
# - Splitting raw text into lyric and tablature info is very basic at the moment.
#   We need a better way to classify & split the various channels (raw tab, lyrics, chords, more?) that can be expected in tablature
#
# @section todo TODO
# - Various prints should be printed at specific log levels, to easily switch between debug, info or warnings only
