# Compilescript for openolat-SASS-theme
# Can be included into eclipse-project-build (project-properties --> "Builders")
# 
# It compiles the whole directory and mostly  all changed files. 
# In the case it does not compile all files, it's helpful to delete the sass-cache (rm -r .sass-cache).
#
# usage:
# ./compiletheme.sh										# compile themes in the current directory
# ./compiletheme.sh /path/to/your/custom/theme			# compile themes in the given directory
# ./compiletheme.sh /path/to/your/custom/themedir		# compile all themes in the given directory
