Vraiment en shell

Ou alors, en restant vraiment en shell (bash 4.0+):

#------------------------------------------------------------------------------
# Parses a .ini file
#
# License:
# GPLv2
#
# Parse the specified .ini file, and stores the results in caller-supplied
# variable arrays:
#
# * +$sections[]+: indexed array
# * +$variables[]+: associative array
# * +$values[]+: associative array
# * +$lines[]+: associative array
#
# Those variables will be filled as thus:
#
# sections=( [0]='section-0' [1]='section-1' )
# variables=( ['section-0']='var-0,var-1' ['section-1']='var-10,var-11' [...] )
# values=( ['section-0:var-0']='value-0-0' ['section-1:var-10']='value-1-10' [...] )
# lines=( ['section-0']='file:27' ['section-1:var-10']='file:42' [...] )
#
# Note that the accepted syntax is a subset of the .ini format, where only
# '=' is accepted to assign variables, while ':' is not accepted.
#
# Param:
# 1ドル: .ini file to parse
#
# Return:
# $sections[] : the list of sections, one section per array index
# $variables[]: the comma-separated list of variables for a section,
# indexed by the name of the section
# $values[] : the value of a variable in a section, indexed by the
# 'section:variable' tuple
# $lines[] : the 'file:line' a section or variable was defined on,
# indexed by the 'section' name, or the 'section:variable'
# tuple
#
