###
### The shell script: import_local.sh
###
### The script copies the source file (param 1) 
### to the destination file (param 2, which is galaxy's dataset_NNNNN.dat).
###
### The extra code tries to make it as safe as possible, allowing imports only
### from limited areas.
###
### The script can be changed from copying to linking - would be even faster.
###
### cpx is a C executable that copies a file from a source to a destination
### only if the source file is readable by the user given in the third arg.
### cpx must be setuid root, so be careful who has access to it!  It can also
### be allowed using sudo, if you know how to do it.
