why not other compet i tors?


django: no!★ less code more magic

★ not so flexible

(specification is growing)

★ using SQLAlchemy within

could be tricky


drupal : no!★ security problems

(370 CVE entries)

★ integration is more difficult

(PHP vs. Python)

★ missing features

workflow, complex ACL, etc.


openerp : hmm★ quite complex: CRM, sales,

accounting and much more

★ not enough time

to fully investigate it

★ not a generic framework
