## A tool for MacOS/Linux(not tested on linux) that compares the differences between generated content of a local docforge PR branch and the master branch:
## 
## 
##        ./diff_check.sh [-c] <local_PR_branch> <remote_name_of_gardener_repo> <path_to_website_generator> 
## 
## 
## With following parameters:
## 
##   -c
##        Optional flag. If present hugo/branchContent directory will not be deleted from website generator folder after tool execution. If flag is omitted the directory will be deleted
## 
##   local_PR_branch
##        The branch name of the PR
## 
##   remote_name_of_gardener_repo
##        Depending from where you have cloned docforge (gardener or your github fork) this most like will be 'origin' or 'upstream' 
## 
##   path_to_website_generator
##        Local path of website generator where content will be generated from 'make build'. Note that the path should contain a 'hugo' folder with a 'content' subfolder and have a 'make build' command defined
## 
## Note: after tool execution docforge binary in /usr/local/bin will be overwritten with the binary of the gardener master branch
##
