It still works well when there is just one argument, as in your example. 
What does not work is any shebang line with more than one argument, as

#!/usr/bin/crm -u /path/to/somewhere

You are completely right. My initial plan for a clean package respecting 
the file hierarchy standard was

/etc/crm114/mailfilter.cf
/etc/crm114/*.mfp
/etc/profile.d/crm114.sh              # adds path to the .crm programs
/usr/bin/(binaries)
/usr/share/crm114/*.crm
/var/lib/crm114/*.css                 # root.users mode=664
/var/lib/crm114/reaver_cache/*        # root.users mode=660
/usr/share/doc/packages/crm114/(docs)

But I have not the slightest idea how this would ever work. I guess 
that I would have to hard-wire all these paths into the package with a 
lot of patches. Ideally, crm114 should run setuid as a special user 
with no login account. Now the package is ugly but functional. :-(
