 # tftpd.remap -- TFTP Daemon Path Remapping

 #

 # This file has three fields: operation, regex, remapping

 #

 # The operation is a combination of the following letters:

 #

 # r - rewrite the matched string with the remapping pattern

 # i - case-insensitive matching

 # g - repeat until no match (used with "r")

 # e - exit (with success) if we match this pattern, do not process

 #     subsequent rules

 # s - start over from the first rule if we match this pattern

 # a - abort (refuse the request) if we match this rule

 # G - this rule applies to TFTP GET requests only

 # P - this rule applies to TFTP PUT requests only

 #

 # The regex is a regular expression in the style of egrep(1).

 #

 # The remapping is a pattern, all characters are verbatim except \

 # \0 copies the full string that matched the regex

 # \1..\9 copies the 9 first (..) expressions in the regex

 # \\ is an escaped \

 #

 # "#" begins a comment, unless \-escaped

 #
