RE: svn_load_dirs.pl for Win32
Hi All,
A further update - properties didn't work properly (because it no longer
uses exec, so the command line does some processing).
Total changes now:
* open(HANDLE, "-|"); doesn't work on Windows. I replaced it with
open(HANDLE, "@commandline |"); on Windows ($^O eq "MSWin32").
* Windows chokes on the multi-line commands. This is caused by
comments and (potentially) properties.
I write these to a temporary file and use --file instead of -m.
* Windows does some processing of the command line so the script
needs to deal with this.
* Windows doesn't define TMPDIR by default. It does define TEMP,
so I use that if TMPDIR isn't found.
