# Indent source code according to GRASS GIS submitting rules

# Should be in sync with:
#     https://trac.osgeo.org/grass/wiki/Submitting/C
#     http://grasswiki.osgeo.org/wiki/Development#Explanation_of_C_indentation_rules

# Dependencies:
#     indent

# Changes and their reasons:
#    -ts8 -ut -> --no-tabs
#        Do not use 8 space wide tabs when indent level is 4

# TODO: replace short flags by long ones to improve readability
