//   PclZip is a PHP library that manage ZIP archives.
11
//   So far tests show that archives generated by PclZip are readable by
12
//   WinZip application and other tools.

  // Description :
239
  //   This method supports two different synopsis. The first one is historical.

  //   This method creates a Zip Archive. The Zip file is created in the
241
  //   filesystem. The files and directories indicated in $p_filelist
242
  //   are added in the archive. See the parameters description for the
243
  //   supported format of $p_filelist.
244
  //   When a directory is in the list, the directory and its content is added
245
  //   in the archive.
246
  //   In this synopsis, the function takes an optional variable list of
247
  //   options. See bellow the supported options.
248
  // Parameters :
249
  //   $p_filelist : An array containing file or directory names, or
250
  //                 a string containing one filename or one directory name, or
251
  //                 a string containing a list of filenames and/or directory
252
  //                 names separated by spaces.
253
  //   $p_add_dir : A path to add before the real path of the archived file,
254
  //                in order to have it memorized in the archive.
255
  //   $p_remove_dir : A path to remove from the real path of the file to archive,
256
  //                   in order to have a shorter path memorized in the archive.
257
  //                   When $p_add_dir and $p_remove_dir are set, $p_remove_dir
258
  //                   is removed first, before $p_add_dir is added.
