Any text file which contains levels and LURD formatted solutions. You can create it without using YSokoban, if your sokoban program can do that. What I need is a text file which contains levels and a solutions for every level after the level. For example
#####
# #
#$ #
### $##
# $ $ #
### # ## # ######
# # ## ##### ..#
# $ $ ..#
##### ### #@## ..#
# #########
#######
Solution:
ullluuuLUllDlld.....
In the above example you can put several solutions for same level. Each of them on one separate line starting with "Solution:" or preceded by a line which is "Solution:"
i.e. either:
Solution:
ullluuuLUllDlld.....
Solution:
urrruu.....
or
Solution: ullluuuLUllDlld.....
Solution: urrruu.....
If there is only one solution then you can omit "Sollution:" at all.
You can send only few levels, there is no need to send solutions only for complete collections.
And you can send several times different solutions for same collection.
If there are new solutions to some levels they will be collected, if you send twice some solution (same solution for some level) this solution will be ignored.
