// --- Draft Formatting

// Papers will be submitted electronically in PDF format via the web submission form.

// 1. Submissions may have at most 12 pages of technical content, including all text, figures, tables, etc. Bibliographic references are not included in the 12-page limit.
// 2. Use A4 or US letter paper size, with all text and figures fitting inside a 178 x 229 mm (7 x 9 in) block centered on the page, using two columns separated by 8 mm (0.33) of whitespace.
// 3. Use 10-point font (typeface Times Roman, Linux Libertine, etc.) on 12-point (single-spaced) leading.
// 4. Graphs and figures should be readable when printed in grayscale, without magnification.

source

We can use the $ORIGIN "special" path to have a path relative to the executable with -Wl,-rpath,'$ORIGIN' in bash or -Wl,-rpath,'$$ORIGIN' in Makefile

note that you need quotes around it to avoid having the shell interpret it as a variable, and if you try to do this in a Makefile, you need $$ to avoid having make interpret the $ as well

// - No longer than 12 single-spaced 8.5" x 11" pages, including figures and tables, plus as many pages as needed for references.
// - Submissions may include as many additional pages as needed for references but not for supplementary material in appendices.
// - Use 10-point type on 12-point (single-spaced) leading and Times Roman or a similar font for the body of the paper.
// - All text and figures fit inside a 7" x 9" (178 mm x 229 mm) block centered on the page, using two columns separated by 0.33" (8 mm) of whitespace. All graphs and figures should be readable when printed in black and white.
// - Papers not meeting these criteria will be rejected without review, and no deadline extensions will be granted for reformatting.
// - Pages should be numbered, and figures and tables should be legible in black and white, without requiring magnification.
// - The paper review process is double-blind. Authors must make a good faith effort to anonymize their submissions, and they should not identify themselves eit
