asymptote: Search paths

 
 2.5 Search paths
 ================
 
 In looking for 'Asymptote' system files, 'asy' will search the following
 paths, in the order listed:
   1. The current directory;
   2. A list of one or more directories specified by the configuration
      variable 'dir' or environment variable 'ASYMPTOTE_DIR' (separated
      by ':' under UNIX and ';' under 'MSDOS');
   3. The directory specified by the environment variable
      'ASYMPTOTE_HOME'; if this variable is not set, the directory '.asy'
      in the user's home directory ('%USERPROFILE%\.asy' under 'MSDOS')
      is used;
   4. The 'Asymptote' system directory (by default,
      '/usr/local/share/asymptote' under 'UNIX' and 'C:\Program
      Files\Asymptote' under 'MSDOS').
