+#Utility for getting options, must be call with source
+#for every <option> it sets a variable 'option_<option>="-"' 
+#if the option appears more than once, it concatenates a "-"
+#if the option contains an argument: 'option_<option>="argument"'
+#if the long option name contains "-" they are converted to "_"
+#params that are not options are stored in 'params'
+#the options to look for is received in the first argument, 
+#a blank separator list with short and long options without the leading - or --
+#options to be stored in the same variable must appear in the same word separated by ':'
+#insert a trailing = if the option requires an argument
+#insert a trailing ? if the option may have an argument NOT IMPLEMENTED
+#option -- means get the rest of argument returned as 'option__=$*'
+
+#example: to allow options -h --help -j -k(with argument) --my-long-option(with argument)
+# and other parameters after -- provide
+#     "help:h j k= my-long-option="
+#parsing "-h -karg pepe --my-long-option=otherar -- -s" will set variables
+#       option_help="-"
+#       option_k="arg"
+#       option_my_long_option="otherarg"
+#       params=" pepe"
+#       option__="-s"
