[Zope] Search and Replace

Hi, I'm considering a search and replace operation in the Data.bbb using a external S&R tool. Are there any particular problems I could run in to? Unfortunately the .bbb files have null-characters in them, and Text Editor can't do S&R in binary mode. Other wise I could have some what more control over the operation. btw. A Search and Replace function would be a nice addition to the manage_find tool. And maybe regular expression? Best Regards, Johan Carlsson
