+# This file contains tu_open and tu_close, which are used to open

+# tu_open -- open a temporary table
+# If the table is to be opened in-place, then it's just opened.
+# Otherwise, a copy of the table is made, and that table is opened
+# read-write.  The name of the original table will be returned as
+# 'tabname' so it can be passed to tu_close, which needs the name of
+# the original file.  If the filename extension is ".tab", then 'table'
+# might not include the extension.  This is the reason we need a
+# separate output argument 'tabname'.  Note, however, that text tables
+# need not have an extension.  If 'table' does not include an extension,
+# and a file of that name exists, then ".tab" will not be appended when
+# copying to 'tabname'.  'tabname' can differ from the actual file name
+# by including a name or number in brackets after the file name.
+#
+# Note that it is an error if readonly=true but inplace=false.
