;; Description: Automate the construction of strace xlat tables.
|

|
|
|

;; Usage: Put point and mark around a set of definitions in a header
|
||
|
|
;; file. Then grab them with C-c G. Switch to the strace source file
|
||
|
|
;; and build the xlat table with C-c B. Then type the name of the table.
