Removes .pl extension from Perl scripts. This may be returned in the future, but it's best to keep the script names unchanged while we merge with the trunk. Tested on: h5committest

|
||
# Purpose: This script will read standard input which should be a
|
||
# function prologue followed by a C function and will emit
|
||
# on standard output the same source code with the function
|
||
# prologue containing documentation for the various errors
|
||
# that occur in the function.
|
||
#
|
||
# Errors are raised by calling HGOTO_ERROR() or
|
||
# HRETURN_ERROR(). The reason for the error message is a
|
||
# comment which appears immediately after the error macro
|
||
# call and is contained entirely on one line:
|
||
#
|
||
# HRETURN_ERROR (...); /*entry not found*/
|
||
#
|
||
# If such a comment doesn't exist, then the previous comment
|
||
# is used, subject to the constraint that raising an error
|
||
# clears the previous comment.
|
||
#
|
||
# /* Entry not found */
|
||
# HGOTO_ERROR (...);

||

|

# c-mark-function and shell-command-on-region functions which
|
||
# are normally bound to M-C-h and M-|.
