# Reads in GET or POST data, converts it to unescaped text, and puts

# Now that cgi scripts can be put in the normal file space, it is useful
# to combine both the form and the script in one place. If no parameters
# are given (i.e., ReadParse returns FALSE), then a form could be output.
# If a reference to a hash is given, then the data will be stored in that
# hash, but the data from $in and @in will become inaccessable.
# If a variable-glob (e.g., *cgi_input) is the first parameter to ReadParse,
# information is stored there, rather than in $in, @in, and %in.
# Second, third, and fourth parameters fill associative arrays analagous to
# %in with data relevant to file uploads.
# If no method is given, the script will process both command-line arguments
# of the form: name=value and any text that is in $ENV{'QUERY_STRING'}
# This is intended to aid debugging and may be changed in future releases

# There are two dividers: the border and the '\r\n\r\n' between
# header and body. Iterate between searching for these
# Retain a buffer of size(bufsize+maxbound); the latter part is
# to ensure that dividers don't get lost by wrapping between two bufs
# Look for a divider in the current batch. If not found, then
# save all of bufsize, move the maxbound extra buffer to the front of
# the buffer, and read in a new bufsize bytes. If a divider is found,
# save everything up to the divider. Then empty the buffer of everything
# up to the end of the divider. Refill buffer to bufsize+maxbound
# Note slightly odd organization. Code before BODY: really goes with
# code following HEAD:, but is put first to 'pre-fill' buffers. BODY:
# is placed before HEAD: because we first need to discard any 'preface,'
# which would be analagous to a body without a preceeding head.
