since I have no publically accessible web space available, I post the
script here (see attachment).
# PRE-COMMIT HOOK
# The pre-commit hook is invoked before a Subversion txn is
# committed. Subversion runs this hook by invoking a program
# (script, executable, binary, etc.) named 'pre-commit' (for which
# this file is a template), with the following ordered arguments:
#  REPOS-PATH (the path to this repository)
#  TXN-NAME (the name of the txn about to be committed)
# The default working directory for the invocation is undefined, so
# the program should set one explicitly if it cares.
# If the hook program exits with success, the txn is committed; but
# if it exits with failure (non-zero), the txn is aborted, no commit
# takes place, and STDERR is returned to the client. The hook
# program can use the 'svnlook' utility to help it examine the txn.
# On a Unix system, the normal procedure is to have 'pre-commit'
# invoke other programs to do the real work, though it may do the
# work itself too.
# *** NOTE: THE HOOK PROGRAM MUST NOT MODIFY THE TXN, EXCEPT ***
# *** FOR REVISION PROPERTIES (like svn:log or svn:author). ***
# This is why we recommend using the read-only 'svnlook' utility.
# In the future, Subversion may enforce the rule that pre-commit
# hooks should not modify the versioned data in txns, or else come
# up with a mechanism to make it safe to do so (by informing the
# committing client of the changes). However, right now neither
# mechanism is implemented, so hook writers just have to be careful.
# Note that 'pre-commit' must be executable by the user(s) who will
# invoke it (typically the user httpd runs as), and that user must
# have filesystem-level permission to access the repository.
# On a Windows system, you should name the hook program
# 'pre-commit.bat' or 'pre-commit.exe',
# but the basic idea is the same.
# Here is an example hook script, for a Unix /bin/sh interpreter:
# Check for modification of tags.
# Reject tag modifications except creation and deletion
