1993-10-26 clasohm 1993-10-26 corrected some spelling mistakes; removed a bug that made it impossible to read theories that don't have a ML file; extended syntax for bases in syntax.ML: a string can be used to specify a theory that is to be read but is not merged into the base (useful for pseudo theories used to document the dependencies of ML files)
1993-10-25 wenzelm 1993-10-25 added white-space; made ~: a fake infix;
1993-10-25 wenzelm 1993-10-25 added white-space; made ~= a fake infix;

1993-10-21 lcp 1993-10-21 simpdata/basify: now calls new fastype_of
1993-10-21 lcp 1993-10-21 logic/mk_equals,mk_flexpair: now calls fastype_of instead of type_of. So it no longer checks t properly -- but it never checked u anyway, and all existing calls are derived from certified terms...
1993-10-21 lcp 1993-10-21 now calls new fastype_of in three places
1993-10-21 lcp 1993-10-21 Pure/Syntax/printer/is_prop: now calls fastype_of1

1993-10-15 clasohm 1993-10-15 file_info now returns a string that does not contain the path/filename (so the string doesn't change when the relative path does)

1993-10-06 clasohm 1993-10-06 changed filenames to lower case name of theory the file contains (only one theory per file, therefore llist.ML has been split)

1993-10-06 clasohm 1993-10-06 changed "list-fn" to "listfn"
