# The "checkoutlist" file is used to support additional version controlled
# administrative files in $CVSROOT/CVSROOT, such as template files.
#
# The first entry on a line is a filename which will be checked out from
# the corresponding RCS file in the $CVSROOT/CVSROOT directory.
# The remainder of the line is an error message to use if the file cannot
# be checked out.
#
# File format:
#
#	[<whitespace>]<filename><whitespace><error message><end-of-line>
#
# comment lines begin with '#'

# The "commitinfo" file is used to control pre-commit checks.
# The filter on the right is invoked with the repository and a list 
# of files to check.  A non-zero exit of the filter program will 
# cause the commit to be aborted.
#
# The first entry on a line is a regular expression which is tested
# against the directory that the change is being committed to, relative
# to the $CVSROOT.  For the first match that is found, then the remainder
# of the line is the name of the filter to run.
#
# If the repository name does not match any of the regular expressions in this
# file, the "DEFAULT" line is used, if it is specified.
#
# If the name "ALL" appears as a regular expression it is always used
# in addition to the first matching regex or "DEFAULT".

# Set this to "no" if pserver shouldn't check system users/passwords
#SystemAuth=no

# Set `PreservePermissions' to `yes' to save file status information
# in the repository.
#PreservePermissions=no

# Set `TopLevelAdmin' to `yes' to create a CVS directory at the top
# level of the new working directory when using the `cvs checkout'
# command.
#TopLevelAdmin=no

# This file affects handling of files based on their names.
#
# The -t/-f options allow one to treat directories of files
# as a single file, or to transform a file in other ways on
# its way in and out of CVS.
#
# The -m option specifies whether CVS attempts to merge files.
#
# The -k option specifies keyword expansion (e.g. -kb for binary).
#
# Format of wrapper file ($CVSROOT/CVSROOT/cvswrappers or .cvswrappers)
#
#  wildcard	[option value][option value]...
#
#  where option is one of
#  -f		from cvs filter		value: path to filter
#  -t		to cvs filter		value: path to filter
#  -m		update methodology	value: MERGE or COPY
#  -k		expansion mode		value: b, o, kkv, &c
#
#  and value is a single-quote delimited value.
# For example:
#*.gif -k 'b'

# The "editinfo" file is used to allow verification of logging
# information.  It works best when a template (as specified in the
# rcsinfo file) is provided for the logging procedure.  Given a
# template with locations for, a bug-id number, a list of people who
# reviewed the code before it can be checked in, and an external
# process to catalog the differences that were code reviewed, the
# following test can be applied to the code:
#
#   Making sure that the entered bug-id number is correct.
#   Validating that the code that was reviewed is indeed the code being
#       checked in (using the bug-id number or a seperate review
#       number to identify this particular code set.).
#
# If any of the above test failed, then the commit would be aborted.
#
# Actions such as mailing a copy of the report to each reviewer are
# better handled by an entry in the loginfo file.
#
# One thing that should be noted is the the ALL keyword is not
# supported.  There can be only one entry that matches a given
# repository.

# The "loginfo" file controls where "cvs commit" log information
# is sent.  The first entry on a line is a regular expression which must match
# the directory that the change is being made to, relative to the
# $CVSROOT.  If a match is found, then the remainder of the line is a filter
# program that should expect log information on its standard input.
#
# If the repository name does not match any of the regular expressions in this
# file, the "DEFAULT" line is used, if it is specified.
#
# If the name ALL appears as a regular expression it is always used
# in addition to the first matching regex or DEFAULT.
#
# You may specify a format string as part of the
# filter.  The string is composed of a `%' followed
# by a single format character, or followed by a set of format
# characters surrounded by `{' and `}' as separators.  The format
# characters are:
#
#   s = file name
#   V = old version number (pre-checkin)
#   v = new version number (post-checkin)
#
# For example:
#DEFAULT (echo ""; id; echo %s; date; cat) >> $CVSROOT/CVSROOT/commitlog
# or
#DEFAULT (echo ""; id; echo %{sVv}; date; cat) >> $CVSROOT/CVSROOT/commitlog

# Three different line formats are valid:
#	key	-a    aliases...
#	key [options] directory
#	key [options] directory files...
#
# Where "options" are composed of:
#	-i prog		Run "prog" on "cvs commit" from top-level of module.
#	-o prog		Run "prog" on "cvs checkout" of module.
#	-e prog		Run "prog" on "cvs export" of module.
#	-t prog		Run "prog" on "cvs rtag" of module.
#	-u prog		Run "prog" on "cvs update" of module.
#	-d dir		Place module in directory "dir" instead of module name.
#	-l		Top-level directory only -- do not recurse.
#
# NOTE:  If you change any of the "Run" options above, you'll have to
# release and re-checkout any working directories of these modules.
#
# And "directory" is a path to a directory relative to $CVSROOT.
#
# The "-a" option specifies an alias.  An alias is interpreted as if
# everything on the right of the "-a" had been typed on the command line.
#
# You can encode a module within a module by using the special '&'
# character to interpose another module into the current module.  This
# can be useful for creating a module that consists of many directories
# spread out over the entire source repository.

# The "notify" file controls where notifications from watches set by
# "cvs watch add" or "cvs edit" are sent.  The first entry on a line is
# a regular expression which is tested against the directory that the
# change is being made to, relative to the $CVSROOT.  If it matches,
# then the remainder of the line is a filter program that should contain
# one occurrence of %s for the user to notify, and information on its
# standard input.
#
# "ALL" or "DEFAULT" can be used in place of the regular expression.
#
# For example:
#ALL mail %s -s "CVS notification"

# The "rcsinfo" file is used to control templates with which the editor
# is invoked on commit and import.
#
# The first entry on a line is a regular expression which is tested
# against the directory that the change is being made to, relative to the
# $CVSROOT.  For the first match that is found, then the remainder of the
# line is the name of the file that contains the template.
#
# If the repository name does not match any of the regular expressions in this
# file, the "DEFAULT" line is used, if it is specified.
#
# If the name "ALL" appears as a regular expression it is always used
# in addition to the first matching regex or "DEFAULT".

# The "taginfo" file is used to control pre-tag checks.
# The filter on the right is invoked with the following arguments:
#
# $1 -- tagname
# $2 -- operation "add" for tag, "mov" for tag -F, and "del" for tag -d
# $3 -- repository
# $4->  file revision [file revision ...]
#
# A non-zero exit of the filter program will cause the tag to be aborted.
#
# The first entry on a line is a regular expression which is tested
# against the directory that the change is being committed to, relative
# to the $CVSROOT.  For the first match that is found, then the remainder
# of the line is the name of the filter to run.
#
# If the repository name does not match any of the regular expressions in this
# file, the "DEFAULT" line is used, if it is specified.
#
# If the name "ALL" appears as a regular expression it is always used
# in addition to the first matching regex or "DEFAULT".

# The "verifymsg" file is used to allow verification of logging
# information.  It works best when a template (as specified in the
# rcsinfo file) is provided for the logging procedure.  Given a
# template with locations for, a bug-id number, a list of people who

##
## Revision 1.51.2.4  2001/03/12 03:59:30  geraint
## SIGINT  (C-c C-c) now causes simulation data to be dumped to MTT.core.
## SIGQUIT (C-c C-\) as for SIGINT, then raises default SIGQUIT.
## SIGFPE  as for SIGINT, then raises default SIGABRT.
##
## Revision 1.51.2.3  2001/03/07 04:06:55  geraint
## Irix: catch SIGFPE and write data before aborting (.exe).
## GNU/Linux: nada.
##
## Revision 1.51.2.2  2001/03/02 00:45:21  geraint
## Separated Euler and Implicit methods in .cc code and dependencies.
