 # A chain of commands to strip and put license into file. If license file contains
 # magic phrase %YEAR%, it will be replaced by file modification years from Git
 # log. Another magic phrase is %AUTHORS%, which will be replaced by authors, who
 # have changed a file according to Git log.
 #
 # usage: putlic.sh target_file license_file [comment] [qualifier] [iors] [find_program] [git_program]
 # example: putlic.sh script.cmake LICENSE "hash" "MYID" "\n" find git
 #
 # parameters:
 # target_file - where to put license.
 # license_file - file containing license.
 # comment - comment type. Passed as "comment" variable to striplic.awk.
 #           Check striplic.awk for possible values.
 # qualifier - copyright notice qualifier. See stiplic.awk for details.
 # iors - input/output record separator (new lines style; typically: "\n" - unix mac "\r\n" - windows).
 # find_program - command to execute findutils find.
 # git_program - command to execute git.
 #
 # required tools: sh, stat, cut, paste, grep, touch, awk, sed, echo, find (findutils), cat, rm, uniq, git, striplic.awk.
