# Setup SVN repository hooks to emulate SVN failures or concurrent commits |

# The function adds |
|
# either pre-commit hook, which causes SVN commit given in second argument |
|
# to fail |
|
# or post-commit hook, which creates a new commit (a new line added to |
|
# auto_updated_file) after given SVN commit |
|
# The first argument contains a type of the hook |
|
# The second argument contains a number (not SVN revision) of commit |
|
# the hook should be applied for (each time the hook is run, the given |
|
# number is decreased by one until it gets 0, in which case the hook |
|
# will execute its real action) |
