*However* - more seriously - if you create a command line tool, then
python *wrongly* handles pathnames.
I've written a command line tool called filestruct that compares a
file structure to a previous state and records the changes (for
remotely syncing directories - you only have to transfer the changes
and then filestruct will make the changes). If you give it a windows
path ending in \" then python interprets it *wrongly*....
D:\Python Projects\directory change >>> filestruct.py compare
"D:\Python Projects\" b:\test.txt b:\test.zip
filestruct needs at least three arguments when run from the command
line. See :
The python interpreter assumes that the entirely valid windows path
supplied at the command line actually contains an escaped quote..... I
may have to write a new command line parser to correct this python
