[IMP] openerp python module.
- Some logging code moved from netsvc.py to loglevels.py - Changed imports to use the new openerp module - config and netsvc initialization calls move to openerp-server.py - Moved openerp-server.py outside the old bin directory - Some imports in tools moved inside the methods to break mutual-dependencies bzr revid: vmt@openerp.com-20110207125723-ooee7d7ng5elmkso

- """Convert a version string to a chronologically-sortable key
-
- This is a rough cross between distutils' StrictVersion and LooseVersion;
- if you give it versions that would work with StrictVersion, then it behaves
- the same; otherwise it acts like a slightly-smarter LooseVersion. It is
- *possible* to create pathological version coding schemes that will fool
- this parser, but they should be very rare in practice.
-
- The returned value will be a tuple of strings. Numeric portions of the
- version are padded to 8 digits so they will compare numerically, but
- without relying on how numbers compare relative to strings. Dots are
- dropped, but dashes are retained. Trailing zeros between alpha segments
- or dashes are suppressed, so that e.g. "2.4.0" is considered the same as
- "2.4". Alphanumeric parts are lower-cased.
-
- The algorithm assumes that strings like "-" and any alpha string that
- alphabetically follows "final" represents a "patch level". So, "2.4-1"
- is assumed to be a branch or patch of "2.4", and therefore "2.4.1" is
- considered newer than "2.4-1", whic in turn is newer than "2.4".
-
- Strings like "a", "b", "c", "alpha", "beta", "candidate" and so on (that
- come before "final" alphabetically) are assumed to be pre-release versions,
- so that the version "2.4" is considered newer than "2.4a1".
-
- Finally, to handle miscellaneous cases, the strings "pre", "preview", and
- "rc" are treated as if they were "c", i.e. as though they were release
- candidates, and therefore are not as new as a version string that does not
- contain them.
