usage: $0 <filematch> [<operation> [<directories>]]
|
|
|
|
<filematch> would typically be "Root"
|
|
|
|
<operation> by default is to transform anonymous access to the psyced
|
|
repository into your personal login access. in detail:
|
|
|
|
"s#^:pserver:anonymous\\\@cvs\\\.psyced\\\.org:/CVS/anonCVS#:pserver:$ENV{USER}\\\@cvs\\\.psyced\\\.org:/CVS/muveCVS#m"
|
|
|
|
without <directories> the directory tree starting from the current directory
|
|
is recursively checked.
|
|
|
|
you can obviously use a completely different regular expression on completely
|
|
different sets of files. for example here is a command that will remove the
|
|
/lastlog store from all of psyced's .o save files it encounters.
|
|
|
|
multipatcher '.o' 's:^_log .*\\n\$::m'
|
|
|
|
you can even embed any of \$name, \$dir or \$base, like this:
|
|
|
|
multipatcher .o 's#softnews#id":"psyc://psyced.org/~$base","softnews#'
|
|
|
|
this one inserts an entry 'id' in front of an existing entry called 'softnews'
