How to tell Bazaar that a file is binary

Question

This is to avoid having some <<< or some >>> in that file if there are conflicts.

If there is a conflict, I just want a message telling me there is a conflict and bazaar should not mess with the file.

With subversion, you can modify the svn:mime-type property. But I don't know if Bazaar have this feature.

Answer 1

The reference says that there is no explicit way of telling so far:

Bazaar currently relies of [sic] content analysis to detect binary files for commands like diff. In the future, a binary = true rule may be added but it is not supported yet.

Answer 2

It is annoying, but you still have the .BASE, .OTHER and .THIS files which are unchanged, you just replace the altered file with the one you need.
Can be scripted, I suppose.
