Mises à part les réunions usuelles, le calendrier indique qu'il y a une réunion Transformers de 14h à 16h. Est-ce que tu auras/vous aurez un créneau compatible avec cet emploi du temps ? Au passage, si vous pouviez présenter (même rapidement) Vcs aux nouveaux, ce serait super !

Vcs: literal `%' in ,form file

by Roland Levillain

The `%' character is has a special meaning in Vcs' ,form files (it is used to form tags like `<%= title %>'). If you forget to escape a literal `%', Vcs produces abstruse error messages : [vcs] info: Creating a new `,iform' file ... [vcs] info: ,form already exists [vcs] error: Removing `,iform' ... [vcs] info: ,form: Contains your complete form (title, subject, ChangeLog entry, diff) [vcs] info: ,log: Contains your Log entry [vcs] error: compile error [vcs] error: (erb):3: parse error, unexpected tGVAR [vcs] error: $erbout_ [vcs] error: ^ Escaping the character with a backslash (`/') solves this problem, but the backslash is left in the ChangeLog! Is there a right way to get a literal `%', or a workaround?
