# Creates a temporally file as usual File object (not Tempfile).

# It don't use finalizer and delegation.

#

# If no block is given, this is similar to Tempfile.new except

# creating File instead of Tempfile.

# The created file is not removed automatically.

# You should use File.unlink to remove it.

#

# If a block is given, then a File object will be constructed,

# and the block is run with said object as argument.

# The File object will be automatically closed and

# the temporally file is removed after the block terminates.

# The call returns the value of the block.

#

# In any case, all arguments (+*args+) will be treated as Tempfile.new.

#

# Tempfile.open2('foo', '/home/temp') do |f|

# ... do something with f ...

# end
