Redmine

I really would like some help getting the OS X project management software Merlin to sync tickets with Redmine. I was told that this can be done through AppleScript. If anyone could help it would really be appreciated, I am new to redmine and know very little about AppleScripting. I found the following but do not understand it:

set issuesFeed to do shell script "curl --insecure " & quoted form of (pathToServer) as «class utf8»

set AppleScript's text item delimiters to {"☃"}
set issuesLines to every text item of issuesFeed
set AppleScript's text item delimiters to {""}

set importedIssues to {}

set deletedIssues to {}

repeat with currentLine in issuesLines

set AppleScript's text item delimiters to {""}
set rawIssueList to every text item of currentLine
