Delete the network route for DESTINATION. For instance, the call:

(delete-network-route sock (make-socket-address AF_INET INADDR_ANY 0))

is equivalent to the 'net-tools' command:

route del -net default

Create a new unique directory in the file system using the template string TMPL and return its file name. TMPL must end with 'XXXXXX'.

Build the given TeX Live package, applying all of PHASES in order.

Retrieve a value from ALIST of alists, descending into each value of the list KEY. For instance a KEY (a b) would retrieve alist[a][b].

Parse and evaluate toml document from file FILE.

Parse and evaluate toml document from string STR.

Build in the OUTPUT directory a symlink tree that is the union of all the INPUTS, using SYMLINK to create symlinks. As a special case, if CREATE-ALL-DIRECTORIES?, creates the subdirectories in the output directory to make sure the caller can modify them later.

When two or more regular files collide, call RESOLVE-COLLISION with the list of colliding files and use the one that it returns; or, if RESOLVE-COLLISION returns #f, skip the faulty file altogether.

Given REFERENCE and FILE, both of which are absolute file names, return the file name of FILE relative to REFERENCE.

(relative-file-name "/gnu/store/foo" "/gnu/store/bin/bar") => "../bin/bar"

Note that this is from a purely lexical standpoint; conversely, ".." is *not* resolved lexically on POSIX in the presence of symlinks.

Patch the `SHELL' variable in FILE, which is supposedly a makefile. When KEEP-MTIME? is true, the atime/mtime of FILE are kept unchanged.

Patch occurrences of "/usr/bin/file" in FILE, replacing them with FILE-COMMAND. When KEEP-MTIME? is true, keep FILE's modification time unchanged.

Insert the KEY/VALUE pair before the first occurrence of a pair whose key is REFERENCE in ALIST. Use KEY=? to compare keys. An error is raised when no such pair exists.

Delete DIR recursively, like `rm -rf', without following symlinks. Don't follow mount points either, unless FOLLOW-MOUNTS? is true. Report but ignore errors.

Return a predicate that returns true when passed a file name whose base name matches REGEXP.

The xz arguments required to enable bit-reproducible, multi-threaded compression.
