Parent-Version: 0.50 Version-Log: Change the way pre are translated in the .env file. Now instead of writting "_pre2toto", one writes "pre(2,toto)". But internally, it is handled the same way as before (i.e., the first thing I do when parsing the env file is to transform "pre(2,toto)" into "_pre2toto" (it makes the hangling of pre vars much more homogeneous with the way the other vars are handled. Also fix a bug where it was not possible to have a pre on input vars because the update_pre was failing to proceed quietly whenever one of its var was not computable because its pre does have a value. Also give an appropriate error message whenever the user wrongly use a pre on a var that can not be computed. Project-Description: Lurette
