--Change working directory to project folder
--The [[bq]] placeholders are replaced by a backquote after merge inserts quotes
--leaving the 'osascript' syntax enclosed in double quotes after merge.
--The command expansion metacharacters make nested quotes legal.
--If the Mac path heirarchy includes a double quote, this method will fail.
--Bash allows an alternate command expansion method...

--Synopsis; ask user to select a file
--               convert Mac path to unix path via 'osascript'
--               get information about the file using 'file -b' and 'file -bi'.
answer file "Select a file"
if it = "" then return ""
put it into macpath
put "`" into bq
--the unshifted tilde (backquote) is at command expansion metacharacter
--the enlosed command is executed and the result served up as a value
put merge("_path=[[bq]]osascript -e 'posix path of alias `[[macpath]]`' | perl -pe 's/ /\ /g' [[bq]] ; ") into cmd
--set the variable '_path' is set to the result of osascript/perl commands
--the osascript command passes the utf8 encoded unix path to perl
--perl replaces spaces with an escape sequence
--the first backslash escapes the 2nd
--the last, escapes <space> itselfi
--oddly, 4-6 backslashes work just well
put "echo -n 'path:' ; " after cmd
--adds a label for following command
put "echo $_path | iconv -f utf8-mac -t macroman | perl -pe 's/\ / /g' ;" after cmd
--pass the _path var to the icon v command for conversion to macroman encoding
--conversion from utf8 is at issue only if the ascii value of a path char is > 127
--the $ symbol before a variable label indicates scalar rather than array variable
--the _path variable remains utf8 encoded
put "echo '' ; " after cmd
--adds a blank line
put "echo 'Info:' `eval file -b $_path` ; " after cmd
--echo prints the char string 'Info:" followed by
--the result of the eval/file command (note the enclosing the backquotes), 
--and a trailing linefeed
--the eval command returns the file command 
--eval allows the path to be resolved from the variable _path
--the file command returns some info about the file
--similar to above...
put "echo -n 'Mime Type:' `eval file -bi $_path`" after cmd
--then -n switch following echo prevents the trailing linefeed
--the -bi switch following 'file'... 
--'-b' prevents path from printing and
--'-i' tell file to return a mime type file descriptor
--execute and display result in alert sheet
