# - Changes from the original (see above url:
|
|
# - if the yaml file contains carriage returns, the processing will fail.
|
|
# - In this case, I made a fix on this line (currently line 14)
|

# -
|
|
# - fs="$(echo @|tr @ '\034')"
|
|
# -
|
|
# - so it became
|
|
# - fs="$(echo @|tr @ '\034'|tr -d '\015')"
|
|

|
|
# - NOTE!
|
|
# - The indent of the yaml configuration file is "2"
|
|
# -
|
|
# - If you want your indentation to be 4 spaces instead of 2 change this line:
|
|
# - indent = length($1)/2;
|
|
# - to be this:
|
|
# - indent = length($1)/4;
