All description in first comments of the script. Maybe my English is not so good (I'm French). Hope anyone will understand.

/* Usage : */
/* Français */
/* À placer dans le prim root (prim coutouré en jaune à l'édition) */
/* Cliquer l'objet pour obtention du menu bleu. */
/* Usage restreint au seul propriétaire. */
/* */
/* English */
/* Place the script in the root prim of the build. */
/* Click the object to get the blue menu. */
/* Usage restricted to the owner. */
/* */
/* Fonctions : */
/* Français */
/* 1) Script de redimensionnement d'un objet multi-prims respectant les */
/* proportions, en taille et en position, de chaque prim. */
/* */
/* 2) Lag minimal puisqu'un seul script par objet (1 à 256 prims) */
/* Possibilité offerte de supprimer le script. */
/* */
/* 3) Communication avec d'autres objets pour synchroniser le redimensionnement */
/* Pour permettre cette communication, plusieurs critères douvent être remplis*/
/* a) L'objet doit être porté ainsi que celui/ceux à synchroniser */
/* b) Les objets doivent porter le même nom, à l'exception de la partie */
/* finale séparée du reste par un espace. */
/* Exemple : Chaussure rouge gauche et Chaussure rouge droite */
/* */
/* 4) Garantie de la conservation de l'intégrité de l'objet. */
/* a) Si un agrandissement entraine une destruction du build, */
/* Retour automatique à la taille avant agrandissement. */
/* */
/* b) Si l'objet contient au moins un huge prim le script reste inactif. */
/* Cette sécurité résevée à la grille officielle SecondLife peut être */
/* désactivée pour opensim en passant à TRUE l'affectation de la variable */
/* globale iAllowResizeHugePrims. */
/* */
/* 5) Prise en compte automatique des changements de liens (ajout/suppresion de */
/* prims ou redimensionnement manuel) */
/* */
/* 6) 18 choix de redimensionnement prédéfinis en pourcentages : */
/* -1, -2, -5, -10, -25, -50, -75, -85, -95. */
/* +1, +2, +5, +10, +25, +50, +75, +100, +200, */
/* */
/* 7) 3 choix extrèmes : Dimensionnement Minimal, Maximal et par Défaut. */
/* La dimension par défaut est celle à l'initialisation du script ou */
/* celle affectée par le menu [Set default]. */
/* */
/* 8) Détermination de la taille maximale avant déformation de la construction */
/* Pour trouver la taille maximale possible, procéder ainsi : */
/* Effectuer des agrandissements à +200% jusqu'à refus de dimensionnement */
/* Répéter l'opération avec les pourcentages inférieurs, +100% puis +75% */
/* puis 50% ... jusqu'à répétition de l'opétation à +1%. */
/* Après un refus de redimensionnement à +1% le script connait la vraie */
/* taille maximale. */
/* */
/* English */
/* 1) Script to resize a multi prims object with conservation of its integrity */
/* (size and relative position of each prim). */
/* */
/* 2) Less lag : only 1 script for an object (1 to 256 prims) */
/* Possibility to remove the script by the menu. */
/* */
/* 3) Communication with other objects to synchronize resize */
/* To allow communication, objects have to comply with few criteria : */
/* a) The object has to be worn, objects to synchronize too. */
/* b) Objects have to have same name except last part separated by space */
/* Example : Excelsior shoes Left and Excelsior shoes Right */
/* */
/* 4) Integrity waranty. */
/* a) If after increasing size the build is broken, automatic go back to */
/* previous good size. */
/* */
/* b) If, at least, one huge prim is in the build, the script is inactive. */
/* This security is only for official grid SecondLife and may be bypassed */
/* for opensim, affecting TRUE to the iAllowResizeHugePrims global variable*/
/* */
/* 5) Automatic detection of manual scale change and link changes */
/* */
/* 6) 18 predefined resize choice in percentage : */
/* -1, -2, -5, -10, -25, -50, -75, -85, -95. */
/* +1, +2, +5, +10, +25, +50, +75, +100, +200, */
/* */
/* 7) 3 other choices : Resize to Minimum, Maximum or Default size. */
/* The default size is the size at initialisation of the script or the size */
/* affected by the blue menu [Set default]. */
/* */
/* 8) How to find the real maximum size ? */
/* To find the real value : */
/* Make an increase size by +200% until the script says it fails. */
/* Then, repeat this method with +100%, then after with +75% ... */
/* After the last increase with +1% the real maximum size is found and */
/* stored by the script. */
